Book ChapterDOI
The Postcentral Somatosensory Cortex
TL;DR: These studies led to several important conclusions: the region of postcentral cortex activated by tactile somatic stimuli includes the separate architectonic fields 3 (3a and 3b), 1 and 2 of Brodmann; the cortex is activated almost exclusively from the contralateral half of the body.
Journal ArticleDOI
Hierarchical Bayesian Modeling and Markov Chain Monte Carlo Sampling for Tuning-Curve Analysis
TL;DR: This work presents a new sampling-based, Bayesian method that allows the estimation of tuning-curve parameters,The estimation of error bars, and hypothesis testing, and provides a useful way of visualizing which tuning curves are compatible with the recorded data.
Book ChapterDOI
Mechanisms of plasticity in the developing and adult visual cortex.
TL;DR: Increasing evidence supports the hypothesis that plasticity in both the developing and adult visual cortex is initiated by a transient reduction of inhibitory drive, and implemented by persistent changes at excitatory synapses.
Journal ArticleDOI
Dynamics of orientation tuning in cat v1 neurons depend on location within layers and orientation maps.

TL;DR: R reverse-correlation analysis of the responses to dynamic grating stimuli is used to re-examine the stability of orientation tuning properties over the timecourse of the response and finds that the preferred orientation and tuning curve shape are stable in the majority of neurons.
Journal ArticleDOI
Representation of the body surface in somatosensory area I of tree shrews, Tupaia glis.
TL;DR: It is concluded that S‐I of tree shrews has both specialized and generalized features, and that the generalized features importantly relate to an understanding of the evolution of the primate somatosensory system.
