Neuron connections in the motor map are linked for the purpose of generating specific movements. These connections are not linked for the purpose of generating specific muscles movements or contractions. [6] Spike-triggered averaging is a way to measure the activity of one cortical motor neuron, on a group of lower motor neurons in the spinal ...
Spinal cord injury research seeks new ways to cure or treat spinal cord injury in order to lessen the debilitating effects of the injury in the short or long term. There is no cure for SCI, and current treatments are mostly focused on spinal cord injury rehabilitation and management of the secondary effects of the condition. [ 1 ]
This leads to the stretching of muscle spindle, activation of alpha motor neurons and finally a partially contracted muscle. The cerebellum is the alpha-gamma motor neuron linkage [citation needed]. Therefore, with the cerebellum the muscle tension is maintained via alpha motor neurons as well as the gamma motor neurons.
Gait analysis is the systematic study of animal locomotion, more specifically the study of human motion, using the eye and the brain of observers, augmented by instrumentation for measuring body movements, body mechanics, and the activity of the muscles. [1]
The effects of neural activity and muscle contraction are highly non-linear, which the nervous system must account for when predicting the consequences of a pattern of motor neuron activity. Much ongoing research is dedicated to investigating how the nervous system deals with these issues, both at the behavioral level, as well as how neural ...
Central pattern generators (CPGs) are self-organizing biological neural circuits [1] [2] that produce rhythmic outputs in the absence of rhythmic input. [3] [4] [5] They are the source of the tightly-coupled patterns of neural activity that drive rhythmic and stereotyped motor behaviors like walking, swimming, breathing, or chewing.
Neural oscillations are commonly studied within a mathematical framework and belong to the field of neurodynamics, an area of research in the cognitive sciences that places a strong focus on the dynamic character of neural activity in describing brain function. [22]
Neuronal activity can be measured with different experimental techniques, such as the "Whole cell" measurement technique, which captures the spiking activity of a single neuron and produces full amplitude action potentials. With extracellular measurement techniques, one or more electrodes are placed in the extracellular space. Spikes, often ...
