Paradigmatic Working Memory (Attractor) Cell in IT Cortex
We discuss paradigmatic properties of the activity of single cells comprising an attractor-a developed stable delay activity distribution. To demonstrate these properties and a methodology for measuring their values, we present a detailed account of the spike activity recorded from a single cell in the inferotemporal cortex of a monkey performing a delayed match-to-sample (DMS) task of visual i...

We discuss paradigmatic properties of activity of single cells comprising an attractor { a developed stable delay activity distribution.

متن کاملAmphetamine Exerts Dose-Dependent Changes in Prefrontal Cortex Attractor Dynamics during Working Memory.
Modulation of neural activity by monoamine neurotransmitters is thought to play an essential role in shaping computational neurodynamics in the neocortex, especially in prefrontal regions. Computational theories propose that monoamines may exert bidirectional (concentration-dependent) effects on cognition by altering prefrontal cortical attractor dynamics according to an inverted U-shaped funct...
متن کاملWorking Memory in the Prefrontal Cortex
The prefrontal cortex participates in a variety of higher cognitive functions. The concept of working memory is now widely used to understand prefrontal functions. Neurophysiological studies have revealed that stimulus-selective delay-period activity is a neural correlate of the mechanism for temporarily maintaining information in working memory processes. The central executive, which is the ma...
متن کاملWorking memory in the primary visual cortex.
T he primary visual cortex is the first cortical area of the visual system that receives information from the external visual world. Neurons in the primary visual cortex have small receptive fields and respond to basic elements of the visual scene. Recent findings, however, show that the primary visual cortex is also involved in cognitive processes, such as visual perception and working memory....
