Subplate and the Formation of the Earliest Cerebral Cortical Circuits
The billions of cells and trillions of connections of the human brain are generated from the complex interactions between a developmental genetic programme and the environment. The resulting embryo is the ultimate readout of our genome; a combination of genetic susceptibility and environmental perturbations can lead to several devastating neurological and psychiatric conditions. The cerebral co...
متن کاملTime in Cortical Circuits.
UNLABELLED Time is central to cognition. However, the neural basis for time-dependent cognition remains poorly understood. We explore how the temporal features of neural activity in cortical circuits and their capacity for plasticity can contribute to time-dependent cognition over short time scales. This neural activity is linked to cognition that operates in the present or anticipates events o...
متن کاملInhibition in cortical circuits
photobleaching reveal that the half-life of stress-granule-associated RNA-binding proteins is very brief, on the order of seconds to minutes, despite the fact that time-lapse microscopy reveals that individual stress granules persist for hours. This rapid shuttling of protein and RNA within stress granules suggests that their mRNP contents are continually sorted via fleeting associations with t...
متن کاملThe asynchronous state in cortical circuits.
Correlated spiking is often observed in cortical circuits, but its functional role is controversial. It is believed that correlations are a consequence of shared inputs between nearby neurons and could severely constrain information decoding. Here we show theoretically that recurrent neural networks can generate an asynchronous state characterized by arbitrarily low mean spiking correlations de...
متن کاملCortical circuits for the control of attention.
How are some thoughts favored over others? A wealth of data at the level of single neurons has yielded candidate brain areas and mechanisms for our best-understood model: visual attention. Recent work has naturally evolved toward efforts at a more integrative, network, understanding. It suggests that focusing attention arises from interactions between widespread cortical and subcortical network...
