Resumen del Recurso

Pregunta 1

Pregunta
Name of the infamous railway worker: [blank_start]Phineas Gage[blank_end]
Respuesta
  • Phineas Gage

Pregunta 2

Pregunta
Prefrontal cortex = Frontal lobe - [blank_start]motor[blank_end] cortex
Respuesta
  • motor

Pregunta 3

Pregunta
The anterior-most part of the PFS is Brodman area [blank_start]10[blank_end], also called anterior PFC or frontal-poler cortex. It is [blank_start]enlarged[blank_end] in humans.
Respuesta
  • 10
  • 4
  • 6
  • 8
  • enlarged
  • smaller

Pregunta 4

Pregunta
Which of these tasks involve the prefrontal cortex?
Respuesta
  • Handling novel, strange, or unusual stimuli or situations
  • Overcoming a strong habitual response or resisting temptation
  • Top-down processing
  • Executive Function
  • Bottom-up processing
  • Understanding speech
  • Fight-and-flight reflexes

Pregunta 5

Pregunta
Humans vs. apes
Respuesta
  • The human PFC is 25 % bigger
  • The human PFC is 25 % more gyrified
  • BA 10 is enlarged
  • BA 10 is smaller
  • The distance between neurons in BA 10 is larger
  • There are more connections between neurons in BA10
  • PFC has 25 % more neurons
  • Neurons in BA 10 are closer together

Pregunta 6

Pregunta
BA 10 is the top of the pyramid, which is looked at from the bird's eye perspective.
Respuesta
  • dorsolateral
  • ventrolateral
  • orbitofrontal

Pregunta 7

Pregunta
FC has connections to [blank_start]unimodal[blank_end] sensory areas [blank_start]and the motor cortex.[blank_end] PFC has connections to [blank_start]multimodal[blank_end] areas[blank_start], e.g. the temporal association cortex.[blank_end]
Respuesta
  • unimodal
  • multimodal
  • and the motor cortex.
  • , e.g. the temporal association cortex.

Pregunta 8

Pregunta
The [blank_start]orbitofrontal[blank_end] cortex is involved in the bottom-up response to reward cues, the anticipation of rewards and the reaction to them. The PFC might play a role in top-down self-regulation but this is controversial and the exact mechanism is most likely more distributed.
Respuesta
  • orbitofrontal
  • ventrolateral
  • dorsolateral

Pregunta 9

Pregunta
Two theories of PFC function: - M[blank_start]ental[blank_end] s[blank_start]ketch[blank_end] p[blank_start]ad[blank_end] (working memory) - C[blank_start]ognitive[blank_end] C[blank_start]ontrol[blank_end] T[blank_start]heory[blank_end] (top-down processing)
Respuesta
  • ental
  • ketch
  • ad
  • ognitive
  • ontrol
  • heory
