Tonic refers to a slow, continuous action. When referenced to tonically active neurons, it is regarded as a continuous firing/discharging at the synapse. Continuous action potentials produced from a neuron qualify it as a tonically active neuron. A great example is fixation neurons in the frontal eye fields and the superior colliculus; when staring directly at a que, these neurons are continuously firing (tonically active), when gaze is diverted from this fixation point during a saccadic eye movement, firing in these neurons show little or no activity. When the short saccade stops, these neurons become tonically active once again (firing consistently.
What else can I help you with?
What has neurons and glial cells?
The nervous system has both. The active cells which carry information are the neurons while the glial cells are the support cells.
What happens with your brain when you think?
It becomes more active. You can see, on an EEG, more "firing" of the neurons.
Why are neurons and muscle cells rich in mitochondria?
Those cells are metabolically very active. So a lot is found
When are mirror neurons active?
Mirror neurons are active when an individual both performs an action and observes someone else performing the same action. They are believed to play a role in empathy, imitation, and understanding others' intentions. Mirror neurons are found in the brain's motor areas, particularly in the premotor cortex and inferior parietal lobule.
Sensory neurons are also known as?
Afferent Neurons
What do neurons have to do with emotions?
Neurons are the active cells of the nervous system. They are used for all cognitive, sense, and manipulatory activities, not just emotions.
Is it neurons that is more than 100 billion active in the brain?
Yes
What has neurons and glial cells?
The nervous system has both. The active cells which carry information are the neurons while the glial cells are the support cells.
What neurotransmitters is released by active neurons to dilate the blood vessels and increase blood flow?
acetylcholine

What are neurons called that detect stimuli in the skin and eye?
sensory neurons
Are neurons that relay impulses from sensory neurons to motor neurons?
Sensory Neurons
Sensory neorons and neurons are connected by-?
Sensory neurons and neurons are connected by Interneurons.
Sensory neurons are also known as?
Afferent Neurons
What are neurons that carry information between sensory neurons and motor neurons?
Interneurons or association neurons.
