purkinje cell Sentence Examples
- Purkinje cells are a type of neuron found in the cerebellum of the brain.
- Named after the Czech anatomist Jan Evangelista Purkyně, Purkinje cells are characterized by their large size and elaborate dendritic arborizations.
- Purkinje cells play a crucial role in motor coordination, receiving inputs from other parts of the brain and integrating them to regulate movements.
- Dysfunction of Purkinje cells can lead to motor disorders such as ataxia, where movements become uncoordinated and clumsy.
- The firing patterns of Purkinje cells are influenced by various neurotransmitters, including gamma-aminobutyric acid (GABA), which inhibits their activity.
- Purkinje cells are inhibitory neurons, meaning they suppress the activity of other neurons within the cerebellar circuitry.
- Research on Purkinje cells has contributed significantly to our understanding of motor control and learning, as they are central to the cerebellar circuitry involved in coordinating movements.
- Purkinje cells have complex dendritic trees that receive inputs from parallel fibers and climbing fibers, which convey sensory and motor information to the cerebellum.
- Purkinje cell degeneration is associated with certain neurodegenerative diseases, such as spinocerebellar ataxia, where the loss of these cells contributes to movement disorders.
- The firing rate and pattern of Purkinje cells are modulated by various factors, including synaptic inputs, intrinsic properties, and neuromodulators, allowing for fine-tuning of motor coordination and learning processes.
