Career

Pennartz studied biology at Radboud University Nijmegen and University of Amsterdam with specializations in neurobiology, philosophy and computational neuroscience. He obtained his PhD degree in Neuroscience cum laude at the University of Amsterdam under the supervision of Fernando Lopes da Silva and Henk Groenewegen. His PhD project and follow-up research examined the physiology and plasticity of brain circuits involved in memory and motivation, focusing on the hippocampus and ventral striatum. [6] [7] [8] [9] [10]

He proceeded to work on computational models of reinforcement learning as a postdoctoral fellow in Computational Neuroscience at the Department of Physics of Computation of the California Institute of Technology with John Hopfield. [11] [12]

In 1994 he initiated research on the cellular electrophysiology of the brain's circadian clock as tenured group leader at the Netherlands Institute for Brain Research. [13] [14]

He uncovered replay of reward information in the ventral striatum during sleep, using in vivo ensemble recordings made with tetrode arrays, a technique he introduced to the Netherlands in collaboration with Bruce McNaughton and Carol Barnes at the University of Arizona (Tucson, U.S.A.) [15] [16] [17]

In 2003 he was appointed professor in Cognitive and Systems Neuroscience at the University of Amsterdam, where he currently leads a group of ~35 people. His main goal is to advance our understanding of multisensory perception, [18] [19] [20] learning and memory [21] [22] [23] [24] [25] and consciousness [26] [27] by integrating experimental, theoretical and computational approaches to neuroscience. To achieve this, the group develops novel techniques for multi-area electrophysiology, [28] computer simulations of brain processes, [29] analytical tools [30] [31] and causal interventions. [32] Pennartz published a theory on consciousness known as Neurorepresentationalism. [33] [34] [35] [36] [37] Using predictive processing principles, [38] this theory characterizes conscious experience as a multimodally rich, spatially encompassing representation of one's world, including one's own body. Recently his work has been ramifying into the clinical domain, studying disorders of consciousness and memory, and into neurotechnology, developing new methods to combat consequences of stroke.

Leadership in science and education; honors and awards

At the University of Amsterdam, he co-develops curricula and courses in Psychobiology (Bachelor), Biomedical Sciences (Bachelor), Brain and Cognitive Sciences (Master) and founded the Master track Cognitive Neurobiology and Clinical Neurophysiology. At the national level, he served for instance as co-leader of the National Science Agenda section on Brain, Behavior & Cognition (Neurolab.nl) with [Eveline Crone] and [Andrea Evers]. Since 2015, he joined the EU FET Flagship Human Brain Project (HBP) [39] through an open call, and continues to lead HBP's Systems and Cognitive Neuroscience Research. Representing these disciplines, he was elected member of the main governing body of HBP, the Scientific and Infrastructure Board. Pennartz received various awards, grants and honours, for example:

The striatum, or corpus striatum, is a nucleus in the subcortical basal ganglia of the forebrain. The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia.

Computational neuroscience is a branch of neuroscience which employs mathematical models, computer simulations, theoretical analysis and abstractions of the brain to understand the principles that govern the development, structure, physiology and cognitive abilities of the nervous system.

<span class="mw-page-title-main">Pyramidal cell</span> Projection neurons in the cerebral cortex and hippocampus

Pyramidal cells, or pyramidal neurons, are a type of multipolar neuron found in areas of the brain including the cerebral cortex, the hippocampus, and the amygdala. Pyramidal cells are the primary excitation units of the mammalian prefrontal cortex and the corticospinal tract. Pyramidal neurons are also one of two cell types where the characteristic sign, Negri bodies, are found in post-mortem rabies infection. Pyramidal neurons were first discovered and studied by Santiago Ramón y Cajal. Since then, studies on pyramidal neurons have focused on topics ranging from neuroplasticity to cognition.

<span class="mw-page-title-main">Nigrostriatal pathway</span>

The nigrostriatal pathway is a bilateral dopaminergic pathway in the brain that connects the substantia nigra pars compacta (SNc) in the midbrain with the dorsal striatum in the forebrain. It is one of the four major dopamine pathways in the brain, and is critical in the production of movement as part of a system called the basal ganglia motor loop. Dopaminergic neurons of this pathway release dopamine from axon terminals that synapse onto GABAergic medium spiny neurons (MSNs), also known as spiny projection neurons (SPNs), located in the striatum.

<span class="mw-page-title-main">Ventral tegmental area</span> Group of neurons on the floor of the midbrain

The ventral tegmental area (VTA), also known as the ventral tegmental area of Tsai, or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain. The VTA is the origin of the dopaminergic cell bodies of the mesocorticolimbic dopamine system and other dopamine pathways; it is widely implicated in the drug and natural reward circuitry of the brain. The VTA plays an important role in a number of processes, including reward cognition and orgasm, among others, as well as several psychiatric disorders. Neurons in the VTA project to numerous areas of the brain, ranging from the prefrontal cortex to the caudal brainstem and several regions in between.

<span class="mw-page-title-main">Motor cortex</span> Region of the cerebral cortex

The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements. The motor cortex is an area of the frontal lobe located in the posterior precentral gyrus immediately anterior to the central sulcus.

A gamma wave or gamma rhythm is a pattern of neural oscillation in humans with a frequency between 25 and 140 Hz, the 40 Hz point being of particular interest. Gamma rhythms are correlated with large scale brain network activity and cognitive phenomena such as working memory, attention, and perceptual grouping, and can be increased in amplitude via meditation or neurostimulation. Altered gamma activity has been observed in many mood and cognitive disorders such as Alzheimer's disease, epilepsy, and schizophrenia. Elevated gamma activity has also been observed in moments preceding death.

Head direction (HD) cells are neurons found in a number of brain regions that increase their firing rates above baseline levels only when the animal's head points in a specific direction. They have been reported in rats, monkeys, mice, chinchillas and bats, but are thought to be common to all mammals, perhaps all vertebrates and perhaps even some invertebrates, and to underlie the "sense of direction". When the animal's head is facing in the cell's "preferred firing direction" these neurons fire at a steady rate, but firing decreases back to baseline rates as the animal's head turns away from the preferred direction.

<span class="mw-page-title-main">Basal forebrain</span> Brain structures in the forebrain

Part of the human brain, the basal forebrain structures are located in the forebrain to the front of and below the striatum. They include the ventral basal ganglia, nucleus basalis, diagonal band of Broca, substantia innominata, and the medial septal nucleus. These structures are important in the production of acetylcholine, which is then distributed widely throughout the brain. The basal forebrain is considered to be the major cholinergic output of the central nervous system (CNS) centred on the output of the nucleus basalis. The presence of non-cholinergic neurons projecting to the cortex have been found to act with the cholinergic neurons to dynamically modulate activity in the cortex.

<span class="mw-page-title-main">Medium spiny neuron</span> Type of GABAergic neuron in the striatum

Medium spiny neurons (MSNs), also known as spiny projection neurons (SPNs), are a special type of GABAergic inhibitory cell representing 95% of neurons within the human striatum, a basal ganglia structure. Medium spiny neurons have two primary phenotypes : D1-type MSNs of the direct pathway and D2-type MSNs of the indirect pathway. Most striatal MSNs contain only D1-type or D2-type dopamine receptors, but a subpopulation of MSNs exhibit both phenotypes.

<span class="mw-page-title-main">Primary motor cortex</span> Brain region

The primary motor cortex is a brain region that in humans is located in the dorsal portion of the frontal lobe. It is the primary region of the motor system and works in association with other motor areas including premotor cortex, the supplementary motor area, posterior parietal cortex, and several subcortical brain regions, to plan and execute voluntary movements. Primary motor cortex is defined anatomically as the region of cortex that contains large neurons known as Betz cells, which, along with other cortical neurons, send long axons down the spinal cord to synapse onto the interneuron circuitry of the spinal cord and also directly onto the alpha motor neurons in the spinal cord which connect to the muscles.

Michael Steven Anthony Graziano is an American scientist and novelist who is currently a professor of Psychology and Neuroscience at Princeton University. His scientific research focuses on the brain basis of awareness. He has proposed the "attention schema" theory, an explanation of how, and for what adaptive advantage, brains attribute the property of awareness to themselves. His previous work focused on how the cerebral cortex monitors the space around the body and controls movement within that space. Notably he has suggested that the classical map of the body in motor cortex, the homunculus, is not correct and is better described as a map of complex actions that make up the behavioral repertoire. His publications on this topic have had a widespread impact among neuroscientists but have also generated controversy. His novels rely partly on his background in psychology and are known for surrealism or magic realism. Graziano also composes music including symphonies and string quartets.

Neural decoding is a neuroscience field concerned with the hypothetical reconstruction of sensory and other stimuli from information that has already been encoded and represented in the brain by networks of neurons. Reconstruction refers to the ability of the researcher to predict what sensory stimuli the subject is receiving based purely on neuron action potentials. Therefore, the main goal of neural decoding is to characterize how the electrical activity of neurons elicit activity and responses in the brain.

Addiction is a state characterized by compulsive engagement in rewarding stimuli, despite adverse consequences. The process of developing an addiction occurs through instrumental learning, which is otherwise known as operant conditioning.
