Acquisition of new skills has the potential to disturb existing network function. To directly assess whether previously acquired cortical function is altered during learning, mice were trained in an abstract task in which selected activity patterns were
The largest targets of retinal input in mammals are the dorsal lateral geniculate nucleus (dLGN), a relay to the primary visual cortex (V1), and the superior colliculus. V1 innervates and influences the superior colliculus. Here, we find that, in turn, s
One key question in system neuroscience is how the brain function is achieved by the dynamic functional connection among different neurons. A neuron receives inputs from the synapses of its connected neurons, and fires action potentials as its output. In the visual cortex, the functional properties...
Fig. 6.6. (A) Recordings from a neuron in the primary visual cortex of a monkey in response to a bar of light moved across the receptive field of the cell (shown by the dashed rectangle) at different angles. (B) Average firing rate of a cat V1 neuron plotted as a function of the...

Visual awareness Consciousness Visual cortex Neural correlate Synchrony Contextual modulation Neuropsychology 1. Introduction In the non-dualistic approach to consciousness, visual awareness is mediated by the activity of nerve cells. The question that is specifically addressed in this paper, is to what ex...

Visual cortex neurons of monkeys and cats: Temporal dynamics of the contrast response function Cortical neurons display two fundamental nonlinear response characteristics: contrast-set gain control (also termed contrast normalization) and response ex... DG Albrecht,WS Geisler,RA Frazor,... - 《...
The basal forebrain provides cholinergic inputs to primary visual cortex (V1) that play a key modulatory role on visual function. While basal forebrain afferents terminate in the infragranular layers of V1, acetylcholine is delivered to more superficial layers through volume transmission. Nevertheless...
