Synaptogenesis in Monkey Somatosensory Cortex
Cerebral Cortex, 1991The time course and rate of synaptogenesis were studied in the somatosensory cortex (Brodmann's areas 1 and 3b) of 27 rhesus monkeys ranging in age from embryonic day 41 to 20 years. Two to four vertical probes, each consisting of a series of overlapping electron micrographs and extending from the pial surface to the interface of the cortex with the ...

Histogenesis of ferret somatosensory cortex
The Journal of Comparative Neurology, 1997The ferret has emerged as an important animal model for the study of neocortical development. Although detailed studies of the birthdates of neurons populating the ferret visual cortex are available, the birthdates of neurons that reside in somatosensory cortex have not been determined. The current study used bromodeoxyuridine to establish when neurons

Spurious dynamics in somatosensory cortex
Behavioural Brain Research, 2002Cortical networks are dynamical systems whose task is to process information. However, in addition to 'intended' dynamical behaviors, the sheer complexity of a cortical network's structure-regardless of its precise details-should generate additional 'unintended' dynamical behaviors.

Rat Navigation by Stimulating Somatosensory Cortex
Journal of Bionic Engineering, 2019One of the most important topics in neuroscience is the issue of brain electrical stimulation and its widespread use. Based on this issue, rat robot, a rat navigation system was introduced in 2002, which has utilized brain electric stimulations as a guide and a reward for driving rats.

Dynamic representations of the somatosensory cortex
Neuroscience & Biobehavioral Reviews, 2010Neural representation of somatosensory events undergoes major transformation in the primary somatosensory cortex (SI) from its original, more or less isomorphic, form found at the level of peripheral receptors. A large body of SI optical imaging, neural recording and psychophysical studies suggests that SI representation of stimuli encountered in ...

Postictal inhibition of the somatosensory cortex
Neurological Sciences, 2010Transient suppression of the motor cortex and of the speech areas cause well-described postictal phenomena following seizures involving the respective cortical areas. Pain is a rare symptom in epileptic seizures. We present a patient with painful tonic seizures in the left leg.

Mammals vary in the number of cortical areas involved in processing somatosensory information. Most mammals appear to have areas S1, S2, and PV, as well as strip-like somatosensory areas along the rostral and caudal borders of S1. In monkeys and other higher primates, cortex caudal to S1 is differentiated into areas 1 and 2, each also representing ...

Somatosensory cortex: a ‘new’ somatotopic representation
Brain Research, 1982A 'new' and orderly representation of the body surface was found in the cerebral cortex of the cat. This somatotopic map was located in the anterior ectosylvian sulcus (AES), an area known to represent several modalities, but believed to be distinguished from primary sensory cortex by its lack of sensory topographies.

Primary somatosensory cortex, cortical somatosensory networks, and cortical somatosensory functions
Pain Forum, 1996Backonja reviews an old, but relevant and ongo ing, problem in cortical somatosensory physiol ogy. What role does the primary somatosen sory cortex (81) play in conscious pain perception? His conclusions, based upon ample evi dence, that 81 is part of a distributed network and that it alone is neither necessary nor sufficient for conscious pain ...

Ipsilateral median somatosensory evoked potentials recorded from human somatosensory cortex
Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1997Somatosensory evoked potentials (SEP) to ipsilateral and contralateral median nerve stimulations were recorded from subdural electrode grids over the perirolandic areas in 41 patients with medically refractory focal epilepsies who underwent evaluation for epilepsy surgery.
