What causes disturbances in sensory neurons?
Disturbances in sensory neurons can be caused by various factors, including physical trauma, inflammation, infection, or chronic conditions such as diabetes. Additionally, certain medications, toxins, or nutritional deficiencies can also lead to dysfunction in sensory neurons.
When neurons fire and transmit messages they?
When neurons fire and transmit messages, they generate electrical signals known as action potentials that travel along their length. These action potentials trigger the release of neurotransmitters at the synapse, allowing communication with other neurons or target cells. This process underlies the function of the nervous system and is essential for various physiological processes such as sensation, movement, and cognition.
Sensory neurons are also known as?
Afferent Neurons
What are neurons that carry information between sensory neurons and motor neurons?
Interneurons or association neurons.
How might mirror neurons play a part in observational learning?
Mirror neurons are believed to be involved in observational learning by mimicking the actions and emotions of others. When observing someone perform a task, mirror neurons may activate in the observer's brain, allowing them to understand and imitate the observed behavior. This process helps individuals learn new skills by watching and modeling the actions of others.
What are neurons that fire when an animal observes an action being preformed by another?
Mirror neurons
What is the best definition for a neurotransmitter?
A neurotransmitter is a chemical messenger that carries signals between neurons in the brain and nervous system. It plays a crucial role in regulating various physiological processes, including mood, cognition, and behavior.
When several neurons are stimulated equally which one will fire first?
The neuron with the lowest threshold potential will fire first when several neurons are stimulated equally. Threshold potential is the minimum level of depolarization needed to trigger an action potential in a neuron. Neurons with lower threshold potentials are more excitable and will fire before neurons with higher threshold potentials.
What disease causes neurons in the brain to die?
Alzheimer's disease
Viral disease that causes destruction of motor neurons?
Poliomyelitis
Do neurons physically changes their position when a person is happy or sad?
No they do not, When you are happy or sad different neurons fire making you feel happy or sad.
What is happening when you are thinking?
When you are thinking, neurons in your brain are firing; they are caused to fire by inputs from the firing of other connected neurons, and the outputs of their firing causes other connected neurons to fire. However, since neurons have MANY MANY connections to many other neurons, any particular neuron is not SIMPLY or absolutely caused to fire just because one connected neuron fires, nor does its firing absolutely cause every neuron it connects to to fire; rather, neurons remember (through physical changes at synapses) which inputs have in combination been strong enough to cause them to fire, making them more sensitive and therefore likely to fire from a variety of similar inputs. Thus thinking is a neuro-chemical memory process, in which memories lead to memories by associations from within and without, and evoke ideas & concepts through novel combinations.
what cell carries messages from nerve cells to your brain?
other nerve cells... The brain is made up of nerve cells (also called neurons). There are neurons both in the central nervous system (the brain and spinal cord) and the peripheral nervous system. The communication between neurons occurs with release of neurotransmitters (chemicals that affect the surface of neurons). The release of neurotransmitters occurs when an electrical impulse travels down the neuron and causes the neuron to "fire" off neurotransmitter. This electrical impulse is called an "action potential." The release of neurotransmitter can have one of two possible effects on the "receiving" neuron, depending on which neurotransmitter binds with which neuron. It can make the receiving neuron either more likely to fire (excitatory) or less likely to fire (inhibitory). The result of this activity in billions of neurons creates quite a symphony, including everything we call thought.
Which theory proposes that above 100 Hz but below 1000 Hz auditory neurons do not fire all at once but in rotation?
The volley principle proposes that auditory neurons do not fire all at once above 100 Hz but below 1000 Hz, but instead fire in a sequential pattern in order to encode pitches. This allows the auditory system to process higher frequencies by distributing the workload among a group of neurons.
Which nervous tissue cells are involved in epilepsy?
Parts of the brain (a nervous tissue) are involved in epilepsy. Some damage of some kind causes the the brain to "fire" irregularly. There are many kinds of epilepsy, see the link below for more information:
What causes the SA node to fire?
The autonomic nervous system causes the SA node to fire
What does the all-or-none law indicate about the behavior of neurons?
The all-or-none law states that a neuron either fires at full strength or does not fire at all in response to a stimulus. This indicates that neurons have a threshold for activation and once that threshold is reached, they will fire with a consistent intensity.
