Which part of the brain is responsible for alarming the brain of danger?
Which part of the brain is responsible for alarming the brain of danger?
The fear response starts in a region of the brain called the amygdala. This almond-shaped set of nuclei in the temporal lobe of the brain is dedicated to detecting the emotional salience of the stimuli – how much something stands out to us.
What part of the brain is most damaged?
If the back part of the frontal lobe (which controls voluntary movements) is damaged, weakness or paralysis can result. Because each side of the brain controls movement of the opposite side of the body, damage to the left hemisphere causes weakness on the right side of the body, and vice versa.
What is the main difference between the cerebral cortex and the lower brain?
Beneath the cerebral cortex is the cerebrum, which serves as the main thought and control center of the brain. It is the seat of higher-level thought like emotions and decision making (as opposed to lower-level thought like balance, movement, and reflexes).
What would happen if there was damage to the cerebral cortex?
Cerebral Cortex Damage: Key Points The cerebral cortex plays a crucial role in nearly all brain functions. Damage to it can cause many cognitive, sensory, and emotional difficulties.
Which is more dangerous the frontal lobes or the base of the brain?
Explain why trauma to the base of the brain is often much more dangerous than trauma to the frontal lobes. (Hint: Think about the relative function of the cerebral hemispheres and the brain stem structures. Which contain centers more vital to life?) tuss
Which is more dangerous a brain hemorrhage or paralysis?
A brain hemorrhage within the region of the right internal capsule results in paralysis of the left side of the body. Explain why the left side (rather than the right side) is affected. Explain why trauma to the brain stem is often much more dangerous than trauma to the frontal lobes.
What happens if you have a brain hemorrhage?
a brain hemorrhage within the region of the right internal capsule results in paralysis of the left side of the body. at the decussation of pyramids in the medulla oblongata, the major motor tracts cross over. frontal lobes = movement, memory, language, problem-solving (not vital to life).
What is the main commissure between the cerebral hemispheres?
IN “SPLIT BRAIN” EXPERIMENTS, THE MAIN COMMISSURE CONNECTING THE CEREBRAL HEMISPHERES IS CUT. FIRST, NAME THE COMMISSURE. 37. DESCRIBE WHAT RESULTS (IN TERMS OF BEHAVIOR) CAN BE ANTICIPATED IN SUCH EXPERIMENTS.
a brain hemorrhage within the region of the right internal capsule results in paralysis of the left side of the body. at the decussation of pyramids in the medulla oblongata, the major motor tracts cross over. frontal lobes = movement, memory, language, problem-solving (not vital to life).
Where does the left side of the brain cross over?
at the decussation of pyramids in the medulla oblongata, the major motor tracts cross over. this means that the right side of the brain controls the motor movements of the left side of the body, so when the right internal capsule is damaged, the left side of the body is affected
Where are the functional areas of the cerebral lobes?
In which of the cerebral lobes (frontal, parietal, occipital, auditory area primary motor area somatic sensory area or temporal) would the following functional areas be found? olfactory area visual area Broca’s area 2. Match the letters on the diagram of the human brain (right lateral view) to the appropriate terms listed at the left: 1.
