Intro, History, Future Flashcards
a multidisciplinary field that combines chemical, biological, and psychological prespectives to better understand neuron structure and function, cognition, emotion and behavior
neuroscience
the “director” that controls interactions between external and internal stimuli
the nervous system
which of the following does the nervous system NOT mediate?
a. thoughts and perceptions
b. bodily movements
c. behaviors
d. the weather
the weather lol
Ancient Egyptians \_\_\_\_\_\_\_\_ the brain after death, think it was unimportant. Early philosophers (~350 BCE) \_\_\_\_\_\_\_ heart was the seat of mental capacity and behaviors. Later philosophers \_\_\_\_\_\_\_\_\_\_\_ the brain is the center of thoughts and emotions. \_\_\_\_\_\_\_ recognized behavioral deficiencies in gladiators with head trauma.
discarded; believed; acknowledged; Galen
the mind and body are distinct and separable
Dualism; Rene Descartes
the mind and the body are the same (mind= physical construct of the brain)
Monism
___ ____ discovered damage to the left temporal lobe results in language deficits
Paul Broca
_____ _____ suffered personality and temperament changes b/c of brain damage (suggests that mental states= brain states)
Phineas Gage
neuroplasticity, social neuroscience, epigenetics, brain health and the microbiome
future areas of research of neuroscience
how biological and social factors affect behavior
social neuroscience
gene changes as you live
epigenetics
how does gut health affect mental health?
brain health + the microbiome
genes change throughout your life
Lazarus POV
nerve cells. the primary cells of the nervous system
neurons
part of the neuron that receives information through the dendrites
input zone
cell body (soma) which integrates the information it receives
integration zone
single axon (nerve fiber) that conducts outpit info away from the cell body as an electrucal impulse
conduction zone
axon terminals at the end of the axon that communicate with other cells
output zone
part of neuron; contains nucleolus and chromosomes
nucleus
part of neuron; semiliquid substance that fills the space of the cell and contains organelles
cytoplasm
part of neuron; produces ATP used for energy
mitochondria
part of neuron; small membranous protrusions where synapses are localized (some of the most plastic structures in the nervous system)
dendritic spine
part of neuron; produce structural support for the neuron; are within the axons within protein strands
microtubules
part of neuron; provide structural support and transmit messages
protein strands (degenerative protein strands are part of the cause of Alzheimer’s)
