Inhibitory Interplay between Orexin Neurons and Eating [PDF]

Current Biology, 2016
In humans and rodents, loss of brain orexin/hypocretin (OH) neurons causes pathological sleepiness [1-4], whereas OH hyperactivity is associated with stress and anxiety [5-10]. OH cell control is thus of considerable interest. OH cells are activated by fasting [11, 12] and proposed to stimulate eating [13].

Function of Dendritic Spines on Hippocampal Inhibitory Neurons [PDF]

Cerebral Cortex, 2013
The majority of γ-aminobutyric acid (GABA)ergic interneurons have smooth dendrites with no or only few dendritic spines, but certain types of spiny GABAergic interneurons do actually contain substantial numbers of spines. The explanation for such spines has so far been purely structural: They increase the dendritic surface area and thus provide the ...

Whole-brain mapping of long-range inputs to the VIP-expressing inhibitory neurons in the primary motor cortex

Frontiers in Neural Circuits, 2023
The primary motor cortex (MOp) is an important site for motor skill learning. Interestingly, neurons in MOp possess reward-related activity, presumably to facilitate reward-based motor learning.

The development and evolution of inhibitory neurons in primate cerebrum [PDF]

Nature, 2022
AbstractNeuroanatomists have long speculated that expanded primate brains contain an increased morphological diversity of inhibitory neurons (INs)1, and recent studies have identified primate-specific neuronal populations at the molecular level2. However, we know little about the developmental mechanisms that specify evolutionarily novel cell types in ...

The Synaptic Organization of Layer 6 Circuits Reveals Inhibition as a Major Output of a Neocortical Sublamina

Cell Reports, 2019
Summary: The canonical cortical microcircuit has principally been defined by interlaminar excitatory connections among the six layers of the neocortex.

Enriched expression of NF1 in inhibitory neurons in both mouse and human brain

Molecular Brain, 2019
Neurofibromatosis type 1 (NF1) is an autosomal dominant disease caused by loss-of-function mutations in NF1 gene, which encodes a GTPase activating protein for RAS.

3D Clustering of GABAergic Neurons Enhances Inhibitory Actions on Excitatory Neurons in the Mouse Visual Cortex

Cell Reports, 2014
Summary: Neocortical neurons with similar functional properties assemble into spatially coherent circuits, but it remains unclear how inhibitory interneurons are organized. We applied in vivo two-photon functional Ca2+ imaging and whole-cell recording of

Muscarinic Acetylcholine Receptor Localization on Distinct Excitatory and Inhibitory Neurons Within the ACC and LPFC of the Rhesus Monkey

Frontiers in Neural Circuits, 2022
Acetylcholine (ACh) can act on pre- and post-synaptic muscarinic receptors (mAChR) in the cortex to influence a myriad of cognitive processes. Two functionally-distinct regions of the prefrontal cortex—the lateral prefrontal cortex (LPFC) and the ...

Spatio-Temporal Sequential Memory Model With Mini-Column Neural Network

Frontiers in Neuroscience, 2021
Memory is an intricate process involving various faculties of the brain and is a central component in human cognition. However, the exact mechanism that brings about memory in our brain remains elusive and the performance of the existing memory models is

Frequency Control in Synchronized Networks of Inhibitory Neurons

Journal of Computational Neuroscience, 1998
We analyze the control of frequency for a synchronized inhibitory neuronal network. The analysis is done for a reduced membrane model with a biophysically-based synaptic influence. We argue that such a reduced model can quantitatively capture the frequency behavior of a larger class of neuronal models.
