What is the all or nothing response of local response?
It's just a way of saying that a neuron (or sensory cell) can either (only) respond or not respond (depending on the strength of the stimuli). Which is why your nervous system is said to be pulse modulated rather than amplitude modulated. OR A strong stimuli results in more pulses, not stronger pulses.
2 Define refractory period and differentiate between absolute and relative refractory periods?
refractory period is the interval between action potential , the absolute refractory period is the period in which second action potential can not be initiated but in relative refractory period the second action potential can be initiated by the more strong stimulus.
Is strong a common noun?
No, the word strong is an adjective, a word to describe a noun, for example a strong odor, a strong rope, a strong will, etc.
How strong is cotton?
Q1. How strong is cotton
What does strong mean?
strong means physically powerful.
What is stimulus response bond theory?
Stimulus-response bond theory proposes that learning occurs through the formation of associations between a stimulus and a response. This theory suggests that repeated pairings of a stimulus with a specific response result in the formation of a strong bond between the two, leading to the learned behavior. It is based on the principles of classical and operant conditioning.
What stimulus below this intensity will result in no response in a neuron?
Any stimulus below the neuron's threshold potential will not result in a response, as it is not strong enough to generate an action potential. Neurons require a minimum level of stimulus intensity to reach the threshold potential and fire an action potential.
The all or none principle states that?
The all-or-none principle in physiology states that once a nerve impulse reaches a certain threshold, a neuron will fire at its maximum potential. If the stimulus is strong enough to trigger an action potential, the response will occur at full strength. If the stimulus is below the threshold, no response will be triggered.
What is an example sentence for exceptionally?
The maths test was exceptionally difficult.The businessman did his job exceptionally well.
When a strong conditioned stimulus is paired with a neutral to become a second conditioned stimulus?
When a strong conditioned stimulus is paired with a neutral stimulus, the neutral stimulus can acquire the ability to elicit the conditioned response even without the presence of the original conditioned stimulus. This process is known as second-order conditioning, where the neutral stimulus becomes a conditioned stimulus through association with the strong conditioned stimulus.
Strong stimuli cause the amplitude of action potentials generated to increase?
Yes, strong stimuli can cause an increase in the amplitude of action potentials generated by neurons. This is known as recruitment of more neurons or an increase in the frequency of action potentials to convey the stronger stimulus information.
Minimum level of stimulation required to trigger a neural impulse?
The minimum level of stimulation required to trigger a neural impulse is known as the "threshold." This threshold is the minimum amount of neurotransmitter release or electrical stimulation needed to generate an action potential in a neuron. Below this threshold, the neuron will not fire an action potential.
What can increase a strong stimulus?
Increasing the intensity or frequency of the stimulus can strengthen its effect. Additionally, increasing the novelty or relevance of the stimulus can also enhance its impact. Finally, pairing the stimulus with a reward or reinforcement can make it more powerful.
According to the if a stimulus causes a strong emotion such as fear an opposite emotion tends to occur when the stimulus ends such as relief?
This phenomenon is known as the contrast effect, where experiencing a strong emotion can lead to a contrasting emotion when the stimulus causing the initial emotion is removed. This emotional shift is a natural response as the body and mind seek balance and equilibrium. It can help individuals adapt to changing circumstances and regulate their emotional states.
What is fiction trigger?
A fiction trigger is an element in a book, movie, or story that evokes a strong emotional response in the audience or reader. It might include themes, scenes, or events that have the power to provoke emotional reactions such as fear, sadness, or excitement.
What is a twitch contraction?
A twitch contraction is a single, brief contraction of a muscle fiber in response to a stimulus. It is the smallest unit of muscle contraction and is not strong enough to produce movement of a limb.
What are the similarities between classical conditioning and one trial learning?
Both classical conditioning and one-trial learning involve associative learning where a new response or behavior is acquired based on the associated stimulus. In classical conditioning, a neutral stimulus becomes associated with a reflex response through repeated pairings. In one-trial learning, a single exposure to a stimulus can lead to a strong and lasting response, indicating rapid acquisition of an association between the stimulus and response.
