Answer:

Michael Gazzaniga and Roger W. Sperry.

Sperry severed the corpus callosum in cats and monkeys to study the function of each side of the brain. He found that if hemispheres were not connected, they functioned independently of one another, which he called a split-brain. The split-brain enabled animals to memorize double the information.

Answer:

Michael Gazzaniga and Roger W. Sperry

Explanation:

Split-brain also known as callosal syndrome was considered successful after it had passed three types of tests to analyze the range of cognitive capabilities of the split-brain subjects. The first was the visual stimulation ability test, the second test was a tactile stimulation situation and the third tested the auditory abilities of the patient.

The mitral valve has fewer flaps than the right atrioventricular valve.<br> a. True<br> b. False
kolezko [41]

Answer:

The mitral valve has fewer flaps than the right atrioventricular valve:

<em>a) True </em>

Explanation:

The mitral valve is a bicuspid valve, which means it has two flaps; whereas, the right atrioventricular valve is a tricuspid valve and so has three flaps.

These two heart valves link the atrium with the ventricles. The mitral valve is located on the left side of the heart, while the tricuspid valve is on the right side.

Which neuron would activate to a muscle? 2. : Which neuron would be found in the retina of the eye? 3. : Which neuron is a senso
lesya [120]

Answer:

Since this question has multiple subquestions in it, I will give you the answer to them as follows:

1. Which neuron would activate a muscle? They are called multipolar neurons, they are found mostly originating from the CNS itself and they are multipolar because when a neuron stimulates a muscle, one signal from just one terminal is not enough; it requires the stimulation from several neurnal terminals.

2. Which neuron would be found in the retina of the eye? A bipolar neuron. This is because these neurons will fulfill a double function: to activate the muscles of the retina, and also they will convey messages taken by the sense of sight, towards the brain for interpretation and integration.

3. Which neuron is a sensory neuron found in a reflex arc? The answer again is a unipolar neuron. These neurons will not reach the brain itself, but rather the reflex arc site on the spinal cord. Their task is to relay sensations from the site that has been stimulated to the spinal cord and from there to the affected place, with the correct response.

4. Which neuron is never myelinated? Again the answer is the bipolar neurons found connecting the retina and the eyes. The reason is that these neurons are capable of relying fast messages to and from the brain, whereas in myelinated ones, messages go slower due to the myeling sheaths.

5. Which neuron is typically involved in the special senses of sight and smell?  Once more the answer is the bipolar neurons that are most commonly found connecting the different organs of these two senses. Since these have such unique capabilities: relying information for integration and sensory and motor responses, their action potentials travel fast, and have a short distance to go.

Which theorist is credited with proposing the psychosexual stages of development?
Naddika [18.5K]

Answer:

Sigmund Freud

Explanation:

Freud proposed that if a child experienced anxiety, that was thwarting his or her sexual appetite during any libidinal (psychosexual) development stage, said anxiety would persist into adulthood as a neurosis (a relatively mild mental illness that is not caused by organic disease, involving symptoms of stress (depression, anxiety, obsessive behavior, hypochondria) but not a radical loss of touch with reality), a functional mental disorder.
