Thalamocortical 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 ...
متن کاملPrimary Somatosensory and Motor Cortex
Figure 1. The gross anatomy of the brain is shown from a lateral (a) and medial (b) view. The wrinkled outer surface that covers the majority of the brain is the cerebral cortex. In panel (a) labels illustrate some of the areas of localized function including primary motor cortex on the precentral gyrus (M1) and primary somatosensory cortex on the postcentral gyrus (S1). Other primary sensory c...
متن کاملBilateral representations of touch in the primary somatosensory cortex.
According to current textbook knowledge, the primary somatosensory cortex (SI) supports unilateral tactile representations, whereas structures beyond SI, in particular the secondary somatosensory cortex (SII), support bilateral tactile representations. However, dexterous and well-coordinated bimanual motor tasks require early integration of bilateral tactile information. Sequential processing, ...
متن کاملProperties of the primary somatosensory cortex projection to the primary motor cortex in the mouse.
The primary somatosensory (S1) and primary motor (M1) cortices are reciprocally connected, and their interaction has long been hypothesized to contribute to coordinated motor output. Very little is known, however, about the nature and synaptic properties of the S1 input to M1. Here we wanted to take advantage of a previously developed sensorimotor slice preparation that preserves much of the S1...
متن کاملPrimary somatosensory cortex hand representation dynamically modulated by motor output.
The brain's primary motor and primary somatosensory cortices are generally viewed as functionally distinct entities. Here we show by means of magnetoencephalography with a phantom-limb patient, that movement of the phantom hand leads to a change in the response of the primary somatosensory cortex to tactile stimulation. This change correlates with the described conscious perception and suggests...
