What are tonically active neurons?
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 happens with your brain when you think?
It becomes more active. You can see, on an EEG, more "firing" of the neurons.
What is happening when you are thinking?
When you are thinking, your brain is actively processing and organizing information in order to generate ideas, solve problems, or make decisions. This process involves complex neural pathways and connections between different regions of the brain, such as the prefrontal cortex, hippocampus, and basal ganglia. Neurotransmitters and electrical signals facilitate communication between neurons, enabling the cognitive processes that occur during thinking.
Which type of neurone transmits the impulse from a motor to a sensory neurone?
No, not directly. Some sensory neurons can detect the effect of a motor neuron firing.
What condition caused by the over firing of neurons in the cerebral cortex?
fuzzy/hazy logic... hyperactivity is another ter, that has been used before
Chemically what are memories?
In the human brain memories are constantly firing neurons. Very basic explanation if you want a more detailed explanation be prepared to read.
How does Valproic acid affect the brain?
Valproic acid is thought to depress activity in certain areas of the brain, suppressing the irregular firing of neurons to prevent seizures
How does the CNS know weather a stimulus is strong or weak?
Nerves do not fire at varying intensities; for example, neurons won't fire at a stronger intensity if you're hit with a baseball in comparison to a marble. The difference between the two stimuli is the number of firing neurons. After being hit with a baseball, the affected neurons will fire more frequently than if hit with a marble.
What are neurons called that detect stimuli in the skin and eye?
sensory neurons
What is the activation -synthesis theory of dreams?
Activation Synthesis Theory is a neurobiological theory of dreams, put forward by Allan Hobson and Robert McCarley in 1977, which states that dreams are a random event caused by firing of neurons in the brain. This random firing sends signals to the body's motor systems, but because of a paralysis that occurs during REM sleep, the brain is faced with a paradox.
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.
