... There is general agreement that commissural projections originate mostly from the homotopic area, and to a lesser extent from neighboring areas [e.g., [6-9]], and involve predominantly neurons in supragranular layers [reviewed in [10-12]]. It has been suggested that geographic distance is a determin ...

Although the molecular, anatomical and functional diversity of ­cortical interneurons is well documented1–3, principal cells are typically grouped together on the basis of their cortical layer and/or subregion assignments. However, several recent observations have suggested that there are distinct s ...

Since the activity of the growth cone has a pronounced influence on the behavior of mitochondria (Morris and Hollenbeck, 1993), we have focused on signals that affect axonal outgrowth, particularly neurotrop ...
The Diversity of Cortical Interneurons
The Diversity of Cortical Interneurons

... It is well established that neurons in the cortex are divided broadly into two major classes: glutamatergic excitatory projection neurons (pyramidal cells) and -aminobutyric acid (GABA)ergic inhibitory local circuit neurons (interneurons). Henceforth, I will refer to interneurons as GABAergic local ...

Premovement neuronal activity

Premovement neuronal activity in neurophysiological literature refers to neuronal modulations that alter the rate at which neurons fire before a subject produces movement. Through experimentation with multiple animals, predominantly monkeys, it has been shown that several regions of the brain are particularly active and involved in initiation and preparation of movement. Two specific membrane potentials, the bereitschaftspotential, or the BP, and contingent negative variation, or the CNV, play a pivotal role in premovement neuronal activity. Both have been shown to be directly involved in planning and initiating movement. Multiple factors are involved with premovement neuronal activity including motor preparation, inhibition of motor response, programming of the target of movement, closed-looped and open-looped tasks, instructed delay periods, short-lead and long-lead changes, and mirror motor neurons.
