What role does the cerebellum play in classical conditioning?
What role does the cerebellum play in classical conditioning?
The cerebellum and its associated circuitry constitutes the entire essential neuronal system for classical conditioning of eye-blink and other discrete responses (e.g. limb flexion) learned with an aversive unconditioned stimulus (US) using the standard delay paradigm where the conditioned stimulus (CS) and the US …
What are the features of cerebellar dysfunction?
Cerebellar dysfunction causes balance problems and gait disorders along with difficulties in coordination resulting in ataxia, uncoordinated movements, imbalance, speech problems(dysarthria), visual problems (nystagmus) and vertigo as a part of the vestibulocerebellar system.
How is the cerebellum involved in the control of movement?
The cerebellum is important for making postural adjustments in order to maintain balance. Through its input from vestibular receptors and proprioceptors, it modulates commands to motor neurons to compensate for shifts in body position or changes in load upon muscles.
What brain region is crucial for classical conditioning?
The cerebellum is necessary for classical conditioning of discrete behavioral responses (eyeblink, limb flexion) under all conditions; however, in the “trace” procedure where a period of no stimuli intervenes between the conditioned stimulus and the unconditioned stimulus the hippocampus plays a critical role.
Which area of the brain is associated with classical conditioning and motor movements?
reticular formation. Which area of the brain is associated with classical conditioning and motor movements? The thalamus: is the brain’s relay station between all of the senses, except smell, and other areas of the brain.
What is a cerebellar infarction?
Introduction. A cerebellar infarct (or cerebellar stroke) is a type of cerebrovascular event involving the posterior cranial fossa, specifically the cerebellum. Impaired perfusion reduces oxygen delivery and causes deficits in motor and balance control.
What does cerebral infarction mean?
Also called ischemic stroke, a cerebral infarction occurs as a result of disrupted blood flow to the brain due to problems with the blood vessels that supply it. A lack of adequate blood supply to brain cells deprives them of oxygen and vital nutrients which can cause parts of the brain to die off.
What happens when the cerebellum is damaged?
Damage to the cerebellum can lead to: 1) loss of coordination of motor movement (asynergia), 2) the inability to judge distance and when to stop (dysmetria), 3) the inability to perform rapid alternating movements (adiadochokinesia), 4) movement tremors (intention tremor), 5) staggering, wide based walking (ataxic gait …
What are the 4 functions of the cerebellum?
The cerebellum controls voluntary movements such as:
- walking.
- posture.
- balance.
- coordination.
- eye movements.
- speech.
