Here is a more comprehensive list of tasks that involve both internal cognitive processes as well as external actions, performed through a combination of basal ganglia and cerebellum neural pathways:
Internal cognitive processes:
– Procedural learning and memory consolidation
– Habit formation
– Coordination of motor planning and execution
– Automaticity of learned skills
– Proceduralization of routines to bypass working memory bottlenecks
– Prediction and timing of motor sequences
– Optimization of movements for fluency and energy efficiency
– Routine cognitive processes like speech, gait, etc.
External actions:
– Fine motor skills and dexterity
– Motor sequencing, choreography of muscle movements
– Balance, postural control
– Eye-hand coordination, visually guided actions
– Rhythmic abilities like dancing, music performance, sports
– Procedural troubleshooting of mechanical/technical problems
– Tool use skills, manipulation of objects
– Walking, manipulating objects in 3D space
– Driving skills and navigation by motor memory
– Procedural memory in languages, times tables, etc.
– Calibration of movements amid external sensory feedback
– Imitation, social motor skills like handshakes, etc.
– Procedural memory for playing musical instruments
– Procedural memory for complex sensorimotor routines
So in summary, basal ganglia and cerebellar circuits appear crucial for both internal cognitive and external motor functions relying on learned, repetitive, automatically triggered skills aided by multisensory feedback processing.
