Direct And Inderect Pathways

Front 1

direct control of movements below the head

Back 1

corticospinal (direct)

Front 2

direct control of movements in the head and neck

Back 2

corticobulbar (direct)

Front 3

upper neurons synapse in red nucleus. similar to comparator function of cerebellum. regulates fine motor control of muscles in distal part of upper limb.

Back 3

rubrospinal (indirect)

Front 4

influence neurons innervating extensor muscles in trunk and proximal portion of lower limbs; help maintain upright posture.

Back 4

Vestibulospinal (indirect)

Front 5

maintenance of posture

Back 5

reticulospinal (indirect)

Front 6

very short-term retention of sensory input

Back 6

working memory (sensory)

Front 7

limited amount of info that can be stored here; only retains information for a few seconds to minutes

Back 7

short term

Front 8

theoretically unlimited space for these memories. accessed by hippocampus (actual memory) (factual information)

Back 8

declarative long term memory

Front 9

implicit or reflexive memory. development of skills such as riding a bicycle. none is really ever lost with this memory. kind of like how i haven't snowboarded in 2 years but i can still do the same tricks i could 2 years ago

Back 9

procedural long term memory

Front 10

memory trace.. series of neurons and their pattern of activity. involved in long term retention of information, a thought, or an idea. Repetition and association of the new information with existing memories assist in transfer of info from short term to long term memory.

Back 10

memory engram
