Answer:the part of the brain that has most likely been damaged in this experiment is the suprachiasmatic nucleus (SCN) found in the hypothalamus of the brain.

Explanation:

circadian rhythms are behavioural changes that respond to light and darkness in an organisms environment. The sleep-inducing wake cycle is a good example of a circadian rhythm. In the experiment, the disruption of the mouse SCN led to development of imbalances in the circadian rhythm of sleep and wake cycle leading to falling asleep and waking up at random times of the day and night. I hope this helps. Thanks

In ________ conditioning, the unconditioned stimulus unconditionally elicits a reaction. For example, a bit of black pepper blow
kipiarov [429]

Answer:

The answer is: Classical Conditioning.

Explanation:

  • According to the theory of Classical Conditioning, an Unconditional Stimulus can be defined as such a stimulus that is capable of triggering a response spontaneously and naturally without the requirement of a previous learning or knowledge about the stimulus.
  • A Neutral stimulus can be defined as such a stimulus which is responsible for drawing or focusing the attention of a person to a particular event.
  • A Conditional Stimulus can be defined as such a stimulus which is generated due to the repeated integration of an Unconditional stimulus to a Neutral stimulus. The repeated integration eventually results in the generation of a conditioned response.
  • In the given example, a bit of black pepper blown into the eyes for the first time is an example of unconditional stimulus. This stimulus initiates a spontaneous or unconditional response, that is, blinking of eyes.
  • But, when this unconditional stimulus gets integrated to the neutral stimulus (irritation in the eyes draws the attention of the person) repeatedly, it can result in the generation of a Conditioned Response (blinking of eyes whenever any foreign object gets into it).

Which statement about neural reflex arcs is incorrect? Which statement about neural reflex arcs is incorrect? Their function is
olchik [2.2K]

Answer:

The incorrect statement is that the neural reflex arc becomes slow by the hormones involved.

Explanation:

A neural pathway that controls a reflex is known as a reflex arc. In a reflex arc, the sensory neuron transmits a signal to the interneuron and stimulates it. The interneuron then transmits or passes the signal to the next neuron, that is, a motor neuron. The motor neuron associates with the interneurons in the spinal cord, which transmits messages from the CNS to the body. Thus, a reflex arc comprises the elements, that is, the receptor, integrating center, and the effector. Their main activity is to protect the body from external events.
