Frontiers in Synaptic Neuroscience, 2019 The ability to adapt to new situations involves behavioral changes expressed either from an innate repertoire, or by acquiring experience through memory consolidation mechanisms, by far a much richer and flexible source of adaptation.

Neuronal Polarity in the Embryonic Mammalian Cerebral Cortex
Frontiers in Cellular Neuroscience, 2017 The cerebral cortex is composed of billions of neurons that can grossly be subdivided into two broad classes: inhibitory GABAergic interneurons and excitatory glutamatergic neurons.

The Ferret as a Model System for Neocortex Development and Evolution
Frontiers in Cell and Developmental Biology, 2021 The neocortex is the largest part of the cerebral cortex and a key structure involved in human behavior and cognition. Comparison of neocortex development across mammals reveals that the proliferative capacity of neural stem and progenitor cells and the ...

State-Dependent Subnetworks of Parvalbumin-Expressing Interneurons in Neocortex. [PDF]
, 2019 Brain state determines patterns of spiking output that underlie behavior. In neocortex, brain state is reflected in the spontaneous activity of the network, which is regulated in part by neuromodulatory input from the brain stem and by local inhibition ...

Brazilian Journal of Medical and Biological Research, 1999 Theta rhythm in many brain structures characterizes wakefulness and desynchronized sleep in most subprimate mammalian brains. In close relation to behaviors, theta frequency and voltage undergo a fine modulation which may involve mobilization of dorsal ...

Topographic hub maps of the human structural neocortical network [PDF]
, 2013 Hubs within the neocortical structural network determined by graph theoretical analysis play a crucial role in brain function. We mapped neocortical hubs topographically, using a sample population of 63 young adults.

Statistical mechanics of neocortical interactions: High resolution path-integral calculation of short-term memory [PDF]
, 1995 We present high-resolution path-integral calculations of a previously developed model of short-term memory in neocortex. These calculations, made possible with supercomputer resources, supplant similar calculations made in L. Ingber, Phys. Rev.

Ubiquitous Neocortical Decoding of Tactile Input Patterns
Frontiers in Cellular Neuroscience, 2019 Whereas functional localization historically has been a key concept in neuroscience, direct neuronal recordings show that input of a particular modality can be recorded well outside its primary receiving areas in the neocortex. Here, we wanted to explore

eLife, 2020 Heterozygous loss of human PAFAH1B1 (coding for LIS1) results in the disruption of neurogenesis and neuronal migration via dysregulation of microtubule (MT) stability and dynein motor function/localization that alters mitotic spindle orientation ...

An Adaptive Threshold in Mammalian Neocortical Evolution
, 2013 Expansion of the neocortex is a hallmark of human evolution. However, it remains an open question what adaptive mechanisms facilitated its expansion.
