The Old Brain: Wired for Survival. The brain stem is the oldest and innermost region of the brain. It’s designed to control the most basic functions of life, including breathing, attention, and motor responses (Figure 4.7, “The Brain Stem and the Thalamus”).
Which region of the brain has the oldest evolutionary history?
With the exception of the spinal cord, these structures are largely located within the hindbrain, diencephalon (or interbrain), and midbrain. These lower dorsal structures are the oldest parts of the brain, having existed for much of its evolutionary history.
Which region of the brain appears to have the oldest evolutionary history and is said to be present in most organisms?
Which region of the brain appears to have the oldest evolutionary history? cerebellum.
Which of the following would be most useful for detecting the exact location of a brain lesion?
Module 4

| Which of the following would be most useful for detecting the exact location of a brain lesion? | a CT scan |
| After suffering an accidental brain injury, Kira has difficulty walking in a smooth and coordinated manner. It is most probable that she has suffered damage to her: | cerebellum. |
Which portion of the cerebral cortex is most directly?
1. Which lobe of the cerebral cortex is most directly involved in speaking? a. occipital lobes.
Which brain structure relays information from the eyes?
Thalamus relays information from the eyes to the visual cortex.
What is the newest brain structure?
The neocortex is the newest part of the cerebral cortex to evolve (prefix neo meaning new); the other part of the cerebral cortex is the allocortex. The cellular organization of the allocortex is different from the six-layered neocortex. In humans, 90% of the cerebral cortex and 76% of the entire brain is neocortex.
What brain part controls emotions?
The limbic system is a group of interconnected structures located deep within the brain. It’s the part of the brain that’s responsible for behavioral and emotional responses.
What part of your brain controls thinking?
The cerebrum, the large, outer part of the brain, controls reading, thinking, learning, speech, emotions and planned muscle movements like walking.
Which part of the brain controls memory?
The main parts of the brain involved with memory are the amygdala, the hippocampus, the cerebellum, and the prefrontal cortex ([link]). The amygdala is involved in fear and fear memories. The hippocampus is associated with declarative and episodic memory as well as recognition memory.
Can blood tests detect brain tumors?
Blood tests can also help in assessing some types of brain tumors, and a lumbar puncture may help in diagnosing metastatic (aggressively spreading) tumors in the brain. A biopsy is a major procedure, and it is the most definitive test for brain tumor diagnosis.
What is a brain scan called?
What is a CT scan of the brain? (Head CT Scan, Intracranial CT Scan) A CT of the brain is a noninvasive diagnostic imaging procedure that uses special X-rays measurements to produce horizontal, or axial, images (often called slices) of the brain.
Does everyone have brain lesions?
Everyone is different and symptoms will vary in individual cases. Many lesions, however, may be in areas of the brain that don’t produce symptoms. Typical symptoms may include: Headaches are usually the first symptom to appear with brain lesions.
Which portion of the cerebral cortex is closest to the ears?
The temporal lobe is one of the four major lobes of the cerebral cortex. It is the lower lobe of the cortex, sitting close to ear level within the skull.
Which lobe of the cerebral cortex is most directly involved in vision?
The Occipital lobe is the portion of the cerebral cortex lying at the back of the head. This area receives information from the visual fields and is associated with vision processing. The forth lobe, the temporal lobe, is the portion of the cerebral cortex laying roughly above the ears.
What is the oldest and most innermost section of the brain?
The brain stem is the oldest and innermost region of the brain. It’s designed to control the most basic functions of life, including breathing, attention, and motor responses (Figure 3.8 “The Brain Stem and the Thalamus”).
