Total questions: 10
Worksheet time: 5mins
Brain mechanisms of vision by Hubel and Wiesel (1979) investigated the architecture of the brain. What specific aspect of the brain did they study?
parietal lobe
visual cortex
cerebellum
temporal lobe
What ethical implications would have been important for their particular study?
Voluntary participation
Debriefing conducted
Animal rights ensuring no harm
The right to withdraw
Hubel and Wiesel won a nobel prize for their discoveries in
neuroscience
psychology
psychiatry
science
What did Hubel & Wiesel use to enable them to describe the key parts of the brain used in visual perception?
Dissections of brains
X-rays
ECGs
Cortical mapping projections
What was Hubel & Wiesel's main finding in regards to the visual cortex?
Visual cortices process images by attaching experience and cognitions to them
Visual cortices are responsible for all visual perception
Visual cortices only work locally on portions of what is seen
Visual cortices do not play a role in visual perception
What is one limitation of Hubel & Wiesel's research?
They only looked at cats
They had a small sample size
The validity and reliability of their research has not been supported by current technology
Their research does not consider the most-up-to-date neuro-structural information
Which aspect within the process of visual perception cannot be explained using Hubel & Wiesel's research
reception
perception
transmission
selection
Broadly, what can be said about the visual cortex?
There are particular stimuli that turn neurons on and off
No stimuli is needed for neurons to turn on
neurons work independently of one another
the layers of the cortex have hundreds of neurons
The main subject of the research discussed in the paper "Brain mechanisms of vision" was....
a cat
a human
a monkey
a rat
In replicating Bernice Grafstein's 1971 work, Hubel and Wiesel found that
their first attempts yielded dismayingly negative results
monkey's produced different results to mice
they were clearly able to trace a path all the way to the cortex
Grafstein's work lacked reliability
