Chapter 4: Neural Morphology Flashcards
how does the brain size of mytecetes compare to odondecetes?
Mysticetes<odontocetes
Explain the ‘big brain evolution’.
- Co-Evolution
- Humans, Whales, Elephants
Social Intelligence Hypothesis
- not challenges in physical environment but social environment (cooperation, coordination, recognition of others, deception) lead to a flexible, intelligent mind.
- social interaction shapes the brain.
name the 7 main areas of the brain
- Telencephaton
- Cranial nerves
- Diencephalon
- Midbrain
- Pons
- Myencephalon
- Cerebellum
Where in the brain will you find optic inputs, processing and receiving center for vestibular and auditory systems, skin sense, and Echo Location?
The midbrain
Where in the brain occurs the inputs to and from regions of the brain to the cerebellum?
Pons
Where does the brain process stress and fine regulation of movement?
Telencephaton
Where in the brain are the ‘thalamus?
What do the ‘thalamuses do?
Diencephalon.
- epi: visceral & pineal control over olfactory reflexes
- sub: etrapyrimidal motor skills
- hypo: endocrine glands, tone, arousal, emotion
- dorsal: sensory & motor info to cerebral cortex
Where are the somatic and visceral nerves? (eyes, tongue, muscle of jaw, face larynx, pharynx)
Myencephalon
Medula oblongata
Where in the brain is the control of the position of the body in space and time, sensorimotor commands?
Cerebellum
Where in the brain is the olfactory nerve, opti nerve large vestibulocochlear nerve? what do they do?
cranial nerves.
- ol: reproduction, secretions, vocalisation.
op: obs.
vesti: brainstem nuclei of auditory system
What class of neurons are responsible for imitation, empathy, language, and theory of mind?
mirror neurons.
Which species share the mirror neurons?
elephants, primates, dolphins, whales, and birds.
where in the brain do they process echolocation?
midbrain
What do seals use to see if females are ripe?
Olfactory
