Abstract:
The human neocerebellum has been hypothesized to contribute to many high-level cognitive processes including attention, language, and working memory. Support for these nonmotor hypotheses comes from evidence demonstrating structural and functional connectivity between the lateral cerebellum and cortical association areas as well as a lack of somatotopy in lobules VI and VII, a hallmark of motor representations in other areas of the cerebellum and cerebral cortex. We set out to test whether somatotopy exists in these lobules by using functional magnetic resonance imaging to measure cerebellar a

Abstract:
The inverse magnification rule in cortical somatotopy is the experimentally derived inverse relationship between cortical magnification (area of somatotopic map representing a unit area of skin surface) and receptive field size (area of restricted skin surface driving a cortical neuron). We show by computer simulation of a simple, multilayer model that Hebb-type synaptic modification subject to competitive constraints is sufficient to account for the inverse magnification rule.

Abstract:
A traditional view of the human motor cortex is that it contains an overlapping sequence of body part representations from the tongue in a ventral location to the foot in a dorsal location. In this study, high-resolution functional MRI (1.5 × 1.5 × 2 mm) was used to examine the somatotopic map in the lateral motor cortex of humans, to determine whether it followed the traditional somatotopic order or whether it contained any violations of that somatotopic order. The arm and hand representation had a complex organization in which the arm was relatively emphasized in two areas: one dorsal and th

Computational models of the somatosensory and auditory systems have been constructed with the neurosimulator GENESIS. The somatosensory model consists of a cortical layer with 1024 pyramidal cells and 512 basket cells connected to a hand surface with 512 tactile receptors. The auditory model consists of a cortical layer with 2256 pyramidal cells and 1128 basket cells connected to a cochlea with 47 receptors. The models reproduce processes related to the formation and maintenance of somatotopic and tonotopic maps and exhibit several features observed in experiments with animals such as variabil

Abstract:
The ability to form an accurate map of sensory input to the brain is an essential aspect of interpreting functional brain signals. Here, we consider the somatotopic map of vibrissa-based touch in the primary somatosensory (vS1) cortex of mice. The vibrissae are represented by a Manhattan-like grid of columnar structures that are separated by inter-digitating septa. The development, dynamics and plasticity of this organization is widely used as a model system. Yet, the exact anatomical position of this organization within the vS1 cortex varies between individual mice. Targeting of a particular

Abstract:
A fundamental trait of intelligent behavior is the ability to respond selectively to stimuli with higher value. Where along the neural hierarchy does somatosensory processing transition from a map of stimulus location to a map of stimulus value? To address this question, we recorded single-unit activity from populations of neurons in somatosensory cortex (S1) and midbrain superior colliculus (SC) in mice conditioned to respond to a positive-valued stimulus and withhold responses to an adjacent, negative-valued stimulus. The stimulus preference of the S1 population was equally weighted towards

The somatotopic organization of spinocervical tract cells and unidentified dorsal horn neurons that lie in the same depth range as the spinocervical tract cells has been examined in detail in the lumbosacral enlargement of cats anesthetized with alpha-chloralose. Only gentle hair movement or light touch of glabrous skin were used as stimuli. Within the region of the dorsal horn containing these neurons there is a precise somatotopic organization. However, there is considerable variation between animals in the relationship between the somatotopic map and the lumbosacral segmental boundaries. Th

Infatti, l'elaborazione degli input sensoriali coinvolge diverse rappresentazioni corporee che influiscono sul modo in cui percepiamo gli oggetti. Numerosi studi hanno dimostrato che l’elaborazione degli stimoli tattili avviene a diversi livelli. Un primo livello coinvolge le mappe somatotopiche, rappresentazioni stabili del corpo che non tengono conto dei cambiamenti posturali. Un secondo livello, coinvolge lo schema corporeo,

Abstract In This Chapter, we will learn the gross structure and functional pathways of the cerebellum. Amazingly, the cerebellum is packed with more neurons than the cerebrum and yet it is able to fit into the compact posterior fossa because of its unique crystalline structure. To learn the anatomy of the cerebellum, we will begin with a mid-sagittal section; then we will create a coronal view of the anterior cerebellum in its folded state; then of the posterior cerebellum in its unfolded state; and afterward, we will learn the cerebellar somatotopic map.

Abstract:
Abstract The brain contains multiple representations of the body. First, afferent inputs from the skin and proprioceptive receptors project to maps of the body surface and body segments, respectively, in the primary somatosensory cortex (Penfield and Rasmussen 1950). These somatotopic maps reflect the distribution of sensory receptors within the body and underpin somatic sensation (Romo et al. 1998). For example, area 3b contains a distorted ‘homunculus’, with enlarged lips and hands.
