PYC3703 - CHAPTER 2:
COGNITIVE NEUROSCIENCE
(EXAM QUESTIONAS AND CORRECT
ANSWERS)
signals are sent from a number of places in the brain
to the motor area, which controls
movement.
cognitive neuroscience
the study of the physiological basis of cognition.
Levels of analysis refers to
the idea that a topic can be studied in a number of
different ways, with each approach contributing its own
dimension to our understanding.
we can study the physiology of cognition at levels
ranging from
the whole brain, to structures within the brain, to chemicals
that create electrical signals within
these structures.
to fully understand any phenomenon
it needs to be studied at different levels of analysis
three methods that have been used to study cognitive
neuroscience:
- recording from single neurons;
- studying the effects of brain damage in humans
- creating images of the brain.
understand the relation between the brain and the
mind, and specifically to understand the physiological
, basis for everything we perceive, remember and think,
it is necessary to look within the brain and observe
the small units called neurons that create and transmit
information about what we experience and know.
The nature of electrical signals in the brain and the
pathways over which they travelled were just
beginning to be discovered in
the 19th century.
To observe the structure of the brain, 19th-century
anatomists applied
special stains to brain tissue, which increased the contrast
between different types of tissue within the brain
nerve net
network was believed to be continuous, like a highway
system in which one street connects directly to another,
but without stop signs or traffic lights
nerve net provided
a complex pathway for conducting signals uninterrupted
through the network
Ramon y Cajal
a Spanish physiologist who used the Golgi stain technique
in newborn animals to more closely investigate the nature
of the nerve net
individual units called neurons were the basic building
blocks of the brain was the centrepiece of the
neuron doctrine
neuron doctrine is the idea that
individual cells transmit signals in the nervous system, and
that these cells are not continuous with other cells as
proposed by the nerve net theory.
