Question 1

How many hippocampuses do humans have?

Answer 1

Humans and other mammals have two hippocampi (correct term for one), one in each side of the brain. It belongs to the limbic system and plays important roles in the consolidation of information from short-term memory to long-term memory and spatial navigation.

Why is it hippocampi and not just hippocampus? People say hippocampus and are referring to it as one. Is hippocampus the plural?

Question 2

How many amygdala do brains have?

Answer 2

The amygdalae (singular: amygdala; /əˈmɪɡdələ/; also corpus amygdaloideum; Latin, from Greek ἀμυγδαλή, amygdalē, ‘almond’, ‘tonsil’[1]), are two almond-shaped groups of nuclei located deep and medially within the temporal lobes of the brain in complex vertebrates, including humans.[2] Shown in research to perform a primary role in the processing of memory, decision-making, and emotional reactions, the amygdalae are considered part of the limbic system.[3]

Question 3

What are raphe nuclei?

Answer 3

The raphe nuclei (“raffe”, Greek: ῥαφή = seam[1] ) are a moderate-size cluster of nuclei found in the brain stem. Their main function is to release serotonin to the rest of the brain.[2] Selective serotonin reuptake inhibitor (SSRI) antidepressants are believed to act in these nuclei, as well as at their targets

Question 4

How can you remember the three columns of the reticular formation?

Answer 4

One is Raphe
Two is red magnifying glass on a cell phone
Three is a golfer marking his score as par

Question 5

What is the median column of the reticular formation?

Answer 5

Raphe Nuclei

Question 6

What is the medial column of the reticular formation?

Answer 6

Magnocellular Red Nuclei

Question 7

What is the lateral column of the reticular formation?

Answer 7

Parvocellular nuclei

Question 8

Why should you use routines and processes as much as possible where possible?

Answer 8

Because you basal ganglia takes over and runs instead of you having to use up energy to think it through

Question 9

What is the Limbic System?

Answer 9

The limbic system (or paleomammalian brain) is a complex set of brain structures located on both sides of the thalamus, right under the cerebrum.[1] It is not a separate system but a collection of structures from the telencephalon, diencephalon, and mesencephalon.[2] It includes the olfactory bulbs, hippocampus, amygdala, anterior thalamic nuclei, fornix, columns of fornix, mammillary body, septum pellucidum, habenular commissure, cingulate gyrus, parahippocampal gyrus, limbic cortex, and limbic midbrain areas.
