Motor cortical activity in a context-recall task.
A monkey was trained to respond on the basis of the serial position of a test stimulus in a sequence. First, three stimuli were presented successively on a circle. Then one of them (except the last) changed color (test stimulus) and served as the go signal: The monkey was required to produce a motor response in the direction of the stimulus that followed the test stimulus. When the test stimulu...
متن کاملReliable recall of spontaneous activity patterns in chaotic cortical networks
Irregular ongoing activity in cortical networks is often modelled as a result of recurrent connectivity. Yet it remains unclear how its presence corrupts the signal transmission evoked by the sensory drive. Here we show that reproducible responses in a generic recurrent cortical-like network can be obtained if the imposed external drive is consistent with patterns previously seen in the spontan...
متن کاملReliable recall of spontaneous activity patterns in cortical networks.
Irregular ongoing activity in cortical networks is often modeled as arising from recurrent connectivity. Yet it remains unclear to what extent its presence corrupts sensory signal transmission and network computational capabilities. In a recurrent cortical-like network, we have determined the activity patterns that are better transmitted and self-sustained by the network. We show that reproduci...
متن کاملDECODING OF TEMPORAL INTERVALS FROM CORTICAL ENSEMBLE ACTIVITY Abbreviated Title: Time Decoding from Cortical Activity
Neurophysiological, neuroimaging and lesion studies point to a highly distributed processing of temporal information by cortico-basal ganglia-thalamic networks. However, there are virtually no experimental data on the encoding of behavioral time by simultaneously recorded cortical ensembles. We predicted temporal intervals from the activity of hundreds of neurons recorded in motor and premotor ...
