Summary
Researchers explore how the brain maps space using place cells and grid cells. This review details advances in understanding spatial mapping in the medial entorhinal cortex and its interaction with the hippocampus.
Area of Science:
- Neuroscience
- Cognitive Science
- Computational Neuroscience
Background:
- The brain's ability to map external space is crucial for navigation and memory.
- Place cells, discovered in 1971, are key components of this spatial representation.
- The origin of the place-cell signal and its formation mechanism remained unclear for decades.
Purpose of the Study:
- To review recent experimental and theoretical progress in understanding spatial mapping within the medial entorhinal cortex (MEC).
- To examine the role of grid cells in explaining the formation of place cells.
- To discuss recent findings on the interactions between the hippocampus and the lateral entorhinal cortex (LEC).
Main Methods:
- Review of recent experimental findings on spatial mapping.
- Analysis of theoretical models explaining neural circuit mechanisms.
- Synthesis of studies investigating hippocampal-entorhinal cortex interactions.
Main Results:
- The discovery of grid cells in the MEC provided a potential circuit mechanism for place cell formation.
- Advances in understanding MEC spatial mapping offer context for place cell origins.
- Studies highlight the interconnectedness of the hippocampus and entorhinal cortex in spatial representation.
Conclusions:
- Spatial mapping in the hippocampal-entorhinal system is a fundamental area of neuroscience research.
- Understanding MEC and LEC interactions is vital for deciphering neural codes of spatial cognition.
- Continued research promises deeper insights into the neural basis of navigation and memory.

4.0K
The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...

01:25Olfaction
49.8K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

01:14Motor and Sensory Areas of the Cortex
8.9K
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex....

01:21Association Areas of the Cortex
10.4K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

The cerebral cortex, a critical structure of the brain, is intricately divided into two hemispheres, each consisting of four distinct lobes: occipital, temporal, frontal, and parietal. These lobes function cooperatively to regulate various cognitive and sensory functions, forming the basis of our complex neural capabilities.
Frontal lobe
The frontal lobes, located behind the forehead, are the command center of our brain, controlling personality, intelligence, and voluntary muscle movements....

01:33Somatosensation
45.2K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
