Attentional Filtering of Visual Information by Neuronal Ensembles in the Primate Lateral Prefrontal Cortex
The activity of neurons in the primate lateral prefrontal cortex (LPFC) is strongly modulated by visual attention. Such a modulation has mostly been documented by averaging the activity of independently recorded neurons over repeated experimental trials. However, in realistic settings, ensembles of simultaneously active LPFC neurons must generate attentional signals on a single-trial basis, des...
متن کاملFast modulation of prefrontal cortex activity by basal forebrain non-cholinergic neuronal ensembles Running title: Basal forebrain modulation of cortical dynamics
Traditionally, most basal forebrain (BF) functions have been attributed to its cholinergic neurons. However, the majority of cortical-projecting BF neurons are non-cholinergic and their in vivo functions remain unclear. We investigated how BF modulates cortical dynamics by simultaneously recording up to 50 BF single neurons along with local field potentials (LFPs) from the prefrontal cortex (PF...
متن کاملEncoding of Spatial Attention by Primate Prefrontal Cortex Neuronal Ensembles
Single neurons in the primate lateral prefrontal cortex (LPFC) encode information about the allocation of visual attention and the features of visual stimuli. However, how this compares to the performance of neuronal ensembles at encoding the same information is poorly understood. Here, we recorded the responses of neuronal ensembles in the LPFC of two macaque monkeys while they performed a tas...
متن کاملTitle : Dynamic Population Coding of Category Information in ITC and PFC Authors :
Most electrophysiology studies analyze the activity of each neuron separately. While such studies have given much insight into properties of the visual system, they have also potentially overlooked important aspects of information coded in changing patterns of activity that are distributed over larger populations of neurons. In this work, we apply a population decoding method, to better estimat...
متن کاملA Quadrantic Bias in Prefrontal Representation of Visual-Mnemonic Space.
Single neurons in primate dorsolateral prefrontal cortex (dLPFC) are known to encode working memory (WM) representations of visual space. Psychophysical studies have shown that the horizontal and vertical meridians of the visual field can bias spatial information maintained in WM. However, most studies and models have tacitly assumed that dLPFC neurons represent mnemonic space homogenously. The...
