Children seem to acquire new know-how in a continuous and open-ended manner. In this paper, we hypothesize that an intrinsic motivation to progress in learning is at the origins of the remarkable structure of children's developmental trajec...

The mammalian brain is characterized by orderly spatial distribution of its cellular components, commonly referred to as topographical organization. The topography of cortical and subcortical maps is thought to represent functional or compu...
Processing of sounds by population spikes in a model of primary auditory cortex [0.03%]

We propose a model of the primary auditory cortex (A1), in which each iso-frequency column is represented by a recurrent neural network with short-term synaptic depression. Such networks can emit Population Spikes, in which most of the neur...

We examined the spatiotemporal dynamics of word processing by recording the electrocorticogram (ECoG) from the lateral frontotemporal cortex of neurosurgical patients chronically implanted with subdural electrode grids. Subjects engaged in ...

Individuals differ in their social status and societies in the extent of social status differences among their members. There is great interest in understanding the key factors that contribute to the establishment of social dominance struct...
Ensembles of gustatory cortical neurons anticipate and discriminate between tastants in a single lick [0.03%]

The gustatory cortex (GC) processes chemosensory and somatosensory information and is involved in learning and anticipation. Previously we found that a subpopulation of GC neurons responded to tastants in a single lick (Stapleton et al., 20...
Dynamics of orientation tuning in cat v1 neurons depend on location within layers and orientation maps [0.03%]

Analysis of the timecourse of the orientation tuning of responses in primary visual cortex (V1) can provide insight into the circuitry underlying tuning. Several studies have examined the temporal evolution of orientation selectivity in V1 ...
Ultrastructure of dendritic spines: correlation between synaptic and spine morphologies [0.03%]

Dendritic spines are critical elements of cortical circuits, since they establish most excitatory synapses. Recent studies have reported correlations between morphological and functional parameters of spines. Specifically, the spine head vo...

The neocortex is spontaneously active, however, the origin of this self-generated, patterned activity remains unknown. To detect potential "pacemaker cells," we use calcium imaging to directly identify neurons that discharge action potentia...
Reciprocal inhibitory connections within a neural network for rotational optic-flow processing [0.03%]

Neurons in the visual system of the blowfly have large receptive fields that are selective for specific optic flow fields. Here, we studied the neural mechanisms underlying flow-field selectivity in proximal Vertical System (VS)-cells, a pa...
