What type of sensory information does conscious relay provide?

Highly accurate, detailed, and precise sensory information.

What are the functions of the sensory information transmitted by conscious relay?

Localization and discrimination.

What pathway(s) is/are related to conscious

- DCML

- spinalthalamic

- trigeminal

What is the primary purpose of divergent thinking?

To grab your attention, elicit arousal, and generate emotional/affective responses.

How does information function in divergent thinking?

It 'diverges' (spreads out) to multiple brain areas.

Is divergent thinking more or less precise?

Less precise.

what pathways are related to divergent

- spinolimbic

-spinoreticular

- spinomesencephalic

What do unconscious pathways transmit?

Sensory information that does not reach conscious awareness.

Which part of the brain primarily uses information from unconscious pathways?

The cerebellum.

unconscious pathways

- Anterior Spinocerebellar Tract

- Posterior Spinocerebellar Tract

- Cuneocerebellar Tract

- Rostrospinocerebellar Tract

What functions are coordinated by the cerebellum using unconscious pathways?

Automatic coordination of movement, posture, and balance.

Posterior Spinocerebellar Tract

legs and lower body, high fideltiy. internal feedback, sensory ascending

Cuneocerebellar Tract

internal feedback, sensory ascending. arms and upper body, high fidelity

Anterior Spinocerebellar Tract

internal feedback, sensory ascending. thoroacolumbar SC, low fidelity, internal feedback

Rostrospinocerebellar Tract

internal feedback, sensory ascending. cervical SC, low fidelity, internal feedback

ataxia

coordination problems

Apraxia

difficulty with planning muscle movements

1st route in CSF

made in chorioid plexus
