Impact of hypokinesia on dynamics of formation of evoked potentials in sensorimotor cortex in early postnatal ontogenesis
The analysis of evoked potentials of sensorimotor cortex in response to electrical stimulation of n. ischiadicus shows that the extremal factor hypokinesia has a negative impact on the dynamics of formation of amplitudal and temporal characteristics since eyes openning in 2-weeks old rats. The most vulnerable process to the impact of hypokinesia is the first-positive phase, which disappears in ...

متن کاملLocalization of sensorimotor cortex in neurosurgery by recording of somatosensory evoked potentials.
The current method of localizing somatosensory and motor cortex during neurosurgical removal of abnormal tissue is Penfield's method of cortical stimulation. While useful, this method has drawbacks, in particular the need to operate under local anesthesia. Another method of localization, described here, involves intra-operative recording of short-latency somatosensory evoked potentials to stimu...

15 صفحه اولThalamocortical connections of the primary somatosensory cortex
Although each subdivision of primary somatosensory cortex (SI) receives dense input from the thalamus, but the exact location and type of information that the fibers convey have not been identified yet. In the present study, the exact source of thalamocortical fibers to areas 2 and 3b was investigated using tract-tracing techniques. Following injection of tracer into area 3b, labeled neurons ...
