A sensory map is an area of the brain which responds to sensory stimulation, and are spatially organized according to some feature of the sensory stimulation. In some cases the sensory map is simply a topographic representation of a sensory surface such as the skin, cochlea, or retina.

functions in the front part of the brain and sensory functions in the rear part of the brain. The image on the right further subdivides the sensory regions to show regions that receive input from somatosensory, auditory, and visual receptors.

A sensory homunculus represents a map of brain areas dedicated to sensory processing for different anatomical divisions of the body. The primary sensory cortex is located in the postcentral gyrus , and handles signals coming from the thalamus .

In neuroanatomy, topographic map is the ordered projection of a sensory surface (like the retina or the skin) or an effector system (like the musculature) to one or more structures of the central nervous system. Topographic maps can be found in all …

In this review, we focus on the structured representation of informational entities in the brain, or the brain’s representational map, as a fundamental mode of organization across different cognitive domains (Behrens et al., 2018; Kriegeskorte and Wei, 2021).

Sep 30, 2024 · Located in the Brain Motor Cortex: Structure, Function, and Role in Movement Control, this map represents how our brain controls movement in different parts of our body. Like its sensory counterpart, the motor homunculus is also disproportionate, but for different reasons.

The brain has many topographical maps, corresponding to the sensory input arrays for vision and touch, and the motor arrays for controlling our skeletal muscles. The body maps shown here are often called the “sensory and motor homunculus” and …

Apr 3, 2013 · Finding how 100 billion neurons make 100 trillion connections. What is being mapped here? Surface area? Also - 0.75 cm and 0.38 cm on a separate card. The two-point discrimination threshold for each body part is reciprocally related to the size of each corresponding homunculus region.

Richly illustrated brain maps including all brain regions, functions and cognitive/ emotional implications.

The brain also houses a map of the outside olfactory world. This map is built by the terminations of olfactory sensory neuron axons within the olfactory bulb. This map operates using three key organizational principles.
