Summary
Neurotransmitter receptor mapping enhances brain mapping by revealing distinct cortical regions and functional systems. This multireceptor approach offers novel insights into brain organization beyond traditional cytoarchitectonics.
Area of Science:
- Neuroscience
- Neuroimaging
- Molecular Biology
Background:
- Cytoarchitectonical brain mapping is crucial for localizing brain activity in functional neuroimaging.
- Neurotransmitter receptors are key molecules in neurotransmission, offering molecular and functional data.
- Understanding receptor distribution provides insights into the human cortex's regional organization.
Purpose of the Study:
- To highlight the relationship between cytoarchitectonical brain maps and the regional distribution of neurotransmitter receptors.
- To demonstrate the potential of receptor mapping for novel, functionally relevant insights into human cortical organization.
- To review the integration of receptor mapping with cytoarchitectonics for a comprehensive brain analysis.
Main Methods:
- Review of existing literature on cytoarchitectonical brain mapping and neurotransmitter receptor distribution.
- Analysis of studies combining functional neuroimaging with receptor mapping techniques.
- Synthesis of data on single and multireceptor mapping in the human cortex.
Main Results:
- Mapping individual receptor types can delineate functionally and cytoarchitectonically distinct cortical regions.
- Combined mapping (receptor fingerprint) reveals the balance of neurotransmitter systems and identifies novel parcellations.
- Different brain regions are identified as components of distinct functional systems based on receptor profiles.
Conclusions:
- Multireceptor mapping offers a multimodal view of the brain's anatomical, functional, and molecular organization.
- It elucidates organizational principles in the segregation of cortical and subcortical structures.
- This approach enhances understanding of brain architecture beyond cytoarchitectonics, aiding clinical and pharmacological studies.

01:23Somatosensory, Motor, and Association Cortex
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 the...
01:14Motor and Sensory Areas of the Cortex
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.

01:33Somatosensation
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.
01:25Olfaction
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.

01:21Association Areas of the Cortex
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,...

01:05Cerebral Hemispheres
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...
