GABA-mediated tonic inhibition differentially modulates gain in functional subtypes of cortical interneurons

Sean Lewis Hill, Christian Andreas Rössert, Bas-Jan Zandt

The binding of GABA (gamma-aminobutyric acid) to extrasynaptic GABA(A) receptors generates tonic inhibition that acts as a powerful modulator of cortical network activity. Despite GABA being present throughout the extracellular space of the brain, previous ...

Octopamine neuron dependent aggression requires dVGLUT from dual-transmitting neurons

Brian Donal McCabe

Neuromodulators such as monoamines are often expressed in neurons that also release at least one fast-acting neurotransmitter. The release of a combination of transmitters provides both "classical" and "modulatory" signals that could produce diverse and/or ...

LTP of inhibition at PV interneuron output synapses requires developmental BMP signaling

Ralf Schneggenburger, Denys Osypenko, Christopher Clark, Evan Dean Vickers

Parvalbumin (PV)-expressing interneurons (PV-INs) mediate well-timed inhibition of cortical principal neurons, and plasticity of these interneurons is involved in map remodeling of primary sensory cortices during critical periods of development. To assess ...

Cortical circuits for transforming whisker sensation into goal-directed licking

Carl Petersen, Sylvain Crochet, Vahid Esmaeili, Georgios Foustoukos, Keita Tamura, Anastasiia Oryshchuk

Animals can learn to use sensory stimuli to generate motor actions in order to obtain rewards. However, the precise neuronal circuits driving learning and execution of a specific goal-directed sensory-to-motor transformation remain to be elucidated. Here, ...

Estimating the Readily-Releasable Vesicle Pool Size at Synaptic Connections in the Neocortex

Henry Markram, Eilif Benjamin Muller, Rodrigo de Campos Perin, Srikanth Ramaswamy, Giuseppe Chindemi, Natali Barros Zulaica

Previous studies based on the 'Quantal Model' for synaptic transmission suggest that neurotransmitter release is mediated by a single release site at individual synaptic contacts in the neocortex. However, recent studies seem to contradict this hypothesis ...

Experimentally-constrained biophysical models of tonic and burst firing modes in thalamocortical neurons

Henry Markram, Sean Lewis Hill, Werner Alfons Hilda Van Geit, Ying Shi, Christian O'Reilly, Christian Andreas Rössert, Elisabetta Iavarone, Bas-Jan Zandt, Jane Yi

Somatosensory thalamocortical (TC) neurons from the ventrobasal (VB) thalamus are central components in the flow of sensory information between the periphery and the cerebral cortex, and participate in the dynamic regulation of thalamocortical states inclu ...

Cellular, Synaptic and Network Effects of Acetylcholine in the Neocortex

Henry Markram, Daniel Keller, Srikanth Ramaswamy, Cristina Colangelo, Polina Shichkova

The neocortex is densely innervated by basal forebrain (BF) cholinergic neurons. Long-range axons of cholinergic neurons regulate higher-order cognitive function and dysfunction in the neocortex by releasing acetylcholine (ACh). ACh release dynamically rec ...

Neurobiological links between stress and anxiety

Maria del Carmen Sandi Perez

Stress and anxiety have intertwined behavioral and neural underpinnings. These commonalities are critical for understanding each state, as well as their mutual interactions. Grasping the mechanisms underlying this bidirectional relationship will have major ...

Norepinephrine stimulates glycogenolysis in astrocytes to fuel neurons with lactate

Pierre Magistretti, Henry Markram, Felix Schürmann, Daniel Keller, Jay Coggan, Corrado Cali

Although efficient compared to computers, the human brain utilizes energy at 10-fold the rate of other organs by mass. How the brain is supplied with sufficient on-demand energy to support its activity in the absence of neuronal storage capacity remains un ...

Stress Impacts the Regulation Neuropeptides in the Rat Hippocampus and Prefrontal Cortex

Aurélie Lattion, Laura Lozano Montes

Adverse life experience increases the lifetime risk to several stress-related psychopathologies, such as anxiety or depressive–like symptom following stress in adulthood. However, the neurochemical modulations triggered by stress have not been fully charac ...

Brain-controlled modulation of spinal circuits improves recovery from spinal cord injury

Silvestro Micera, Grégoire Courtine, Marco Bonizzato, Natalia Pavlova, Galyna Pidpruzhnykova

The delivery of brain-controlled neuromodulation therapies during motor rehabilitation may augment recovery from neurological disorders. To test this hypothesis, we conceived a brain-controlled neuromodulation therapy that combines the technical and practi ...
