Cortical minicolumn
Cortical minicolumns are vertical columns of neurons in the brain's cerebral cortex that are thought to act as a single functional unit. They are a basic unit of organization in the cerebral cortex and are composed of approximately 80-120 neurons.
Structure[edit | edit source]
The structure of a cortical minicolumn consists of a group of neurons stacked on top of each other from the pia mater to the white matter. These neurons are interconnected in a vertical fashion, with each neuron in the column responding to the same type of sensory stimuli. The neurons within a minicolumn are more strongly interconnected with each other than with neurons in adjacent minicolumns.
Function[edit | edit source]
The function of cortical minicolumns is not fully understood, but they are thought to play a key role in information processing in the brain. Each minicolumn is believed to process a small piece of information, and the combined activity of many minicolumns allows for complex cognitive functions.
Clinical significance[edit | edit source]
Abnormalities in cortical minicolumns have been implicated in a number of neurological and psychiatric disorders, including autism, schizophrenia, and Alzheimer's disease. In these conditions, the structure and function of minicolumns may be altered, leading to disruptions in information processing.
