'Diversity and Function of Somatostatin-Expressing Interneurons in the Cerebral Cortex'. In the cerebellum Purkinje cells and interneuronal Golgi cells predominate. In the cerebral cortex different neurons occupy the different cortical layers and include the pyramidal neurons and rosehip neurons. A cause of the disruption can occur in prenatal development through the exposure to chemicals and environment. Disruption of this balance is a common feature of neuropsychiatric disorders such as schizophrenia. Cortical interneurons vary in shape, molecular make-up, and electrophysiology they function collectively to maintain the balance between excitation and inhibition in the cortex primarily through the use of GABA. Ĭortical interneurons only make up around a fifth of the neuronal population but they play a major role in modulating cortical activity needed for cognition and many aspects of learning and memory. Neurons may be termed by their associated neurotransmitter such as excitatory dopaminergic neurons and inhibitory GABAergic neurons. Neurons communicate with other neurons using neurotransmitters released from their synapses, and they may be inhibitory, excitatory or neuromodulatory. They can also synthesise membrane and protein. Neurons are polarised cells that are specialised for the conduction of action potentials also called nerve impulses. There are an estimated 100 billion neurons in the human brain.

They can only function in collaboration with other neurons and interneurons in a neural circuit. Neurons, also called nerve cells, are the functional electrically excitable cells of the brain. Astrocytes are seen to be capable of communication with neurons involving a signalling process similar to neurotransmission called gliotransmission. Glia are grouped into macroglia of astrocytes, ependymal cells, and oligodendrocytes, and much small microglia. Glia are the supporting cells of the neurons and have many functions not all of which are clearly understood, but include providing support and nutrients to the neurons. Nuclei are connected to other nuclei by tracts of white matter. Neurons are often grouped into a cluster known as a nucleus where they usually have roughly similar connections and functions. The two main neuronal classes in the cerebral cortex are excitatory projection neurons, and inhibitory interneurons around 70-80 per cent are neurons, and 20-30 per cent inhibitory interneurons. Neurons are the excitable cells of the brain that function by communicating with other neurons and interneurons (via synapses), in neural circuits and larger brain networks. The two main types of cells in the brain are neurons, also known as nerve cells, and glial cells also known as neuroglia. The rest of the brain tissue is structural or connective called the stroma which includes blood vessels. Brain cells make up the functional tissue of the brain.
