Neuronal tuning refers to the hypothesized property of brain cells by which they selectively represent a particular type of sensory, association, motor, or cognitive information. Some neuronal responses have been hypothesized to be optimally tuned to specific patterns through experience. Neuronal tuning can be strong and sharp, as observed in primary visual cortex (area V1) (but see Carandini et al 2005 ), or weak and broad, as observed in neural ensembles.

WebJun 13, 2024 · It was suggested that MRS GABA signals are likely to reflect extracellular GABA, pointing to the possibility that a kind of non-synaptic intracortical inhibition might work to enhance sensory tuning; namely, tonic inhibition functions when extracellular GABA molecules activate extrasynaptic GABA receptors.

WebWhat is broad tuning? Sensory and motor variables are typically represented by a population of broadly tuned neurons. A coarser representation with broader tuning can often … WebMar 21, 2006 · Introduction. Since the earliest studies of sensory systems [ 1], the contribution of individual neurons to sensory function has been assessed by measuring their responses to a relevant set of stimuli.The standard tool in performing this characterization is the neuronal tuning curve: a plot of the average firing rate of the neuron as a function of … WebTuning curves are widely used to characterize the responses of sensory neurons to external stimuli, but there is an ongoing debate as to their role in sensory processing. Commonly, it … thurbers fantasist
