Spatial pattern of intra-laminar connectivity in supragranular mouse auditory cortex
Neuronal responses and topographic organization of feature selectivity in the cerebral cortex are shaped by ascending inputs and by intracortical connectivity. The mammalian primary auditory cortex has a tonotopic arrangement at large spatial scales (greater than 300 microns). This large-scale architecture breaks down in supragranular layers at smaller scales (around 300 microns), where nearby ...
متن کاملColumnar Connectivity and Laminar Processing in Cat Primary Auditory Cortex
BACKGROUND Radial intra- and interlaminar connections form a basic microcircuit in primary auditory cortex (AI) that extracts acoustic information and distributes it to cortical and subcortical networks. Though the structure of this microcircuit is known, we do not know how the functional connectivity between layers relates to laminar processing. METHODOLOGY/PRINCIPAL FINDINGS We studied the ...
متن کاملCholinergic synaptic potentials in the supragranular layers of auditory cortex.
Receptive-field plasticity within the auditory neocortex is associated with learning, memory, and acetylcholine (ACh). However, the interplay of elements involved in changing receptive-fields remains unclear. Herein, we describe a depolarizing and a hyperpolarizing potential elicited by repetitive stimulation (20-100 Hz, 0.5-2 sec) and dependent on ACh, which may be involved in modifying recept...
متن کاملSpatial profile of excitatory and inhibitory synaptic connectivity in mouse primary auditory cortex.
The role of local cortical activity in shaping neuronal responses is controversial. Among other questions, it is unknown how the diverse response patterns reported in vivo-lateral inhibition in some cases, approximately balanced excitation and inhibition (co-tuning) in others-compare to the local spread of synaptic connectivity. Excitatory and inhibitory activity might cancel each other out, or...
متن کاملLaminar transformation of frequency organization in auditory cortex.
The mammalian neocortex is a six-layered structure organized into radial columns. Within sensory cortical areas, information enters in the thalamorecipient layer and is further processed in supragranular and infragranular layers. Within the neocortex, topographic maps of stimulus features are present, but whether topographic patterns of active neurons change between laminae is unknown. Here, we...
