Vision No.13

What happens if strasbismus (both eyes do not align) occurs during critical period?

We can help strabismus by placing a patch on the good eye, this forces the poor eye to be used. However the eyes will not become fully aligned and it doesn't work on stereopsis (seeing in depth)

Filters work for migranes and prevention of seizures. Which one of these is evidence?

Damage to which area causes dyslexia?

Autism, dyslexia and Schizophrenia are linked.

NMJs are excitatory synapses that use voltage-gated calcium channels to release the neurotransmitter acetylcholine

Inhibition over time results in all of the following except?

Which Brodmann area reflects the primary motor cortex?

Prolonged stimulation of the primary motor cortex would be expected to cause which movement?

An individual has had a stroke and is able to perform individual movements but struggles with sequential movements such as typing a phone number. What brain area do you think has been affected?

Strabismus and Its Implications

Strabismus, characterized by misaligned eyes, disrupts normal vision development during the critical period of visual maturation.
Patching the dominant eye encourages the use of the weaker eye but may not achieve full alignment or restore stereopsis (depth perception).

Treatment and Effects

Filters can alleviate migraine symptoms and act as preventive measures against seizures, highlighting their therapeutic applications.

Neurological Conditions

Dyslexia is associated with damage to specific areas in the brain, including the left temporoparietal region.
Autism, dyslexia, and schizophrenia share neurological links, suggesting overlapping genetic or environmental factors.

Neuromuscular Junctions

Neuromuscular junctions (NMJs) function as excitatory synapses, utilizing voltage-gated calcium channels to release acetylcholine, essential for muscle contraction.

Inhibition and Its Consequences

Prolonged inhibition can lead to various outcomes, but one exception may be a specific neurological effect that does not manifest similarly.

Primary Motor Cortex

Brodmann area 4 corresponds to the primary motor cortex, responsible for voluntary motor function.
Extended stimulation of the primary motor cortex typically results in involuntary movements or muscle contractions, indicating cortical responsiveness.

Stroke and Movement Disorder

Individuals recovering from a stroke may succeed with isolated movements yet face challenges in executing sequential tasks, like typing, indicating affected neural pathways in the motor control areas.
