Summary: The amygdala, usually linked to storage, also plays a vital role in qualified actions like coding, handwriting, and playing music. This study challenges the long-held misconception that basal ganglia and brain are the only motor regions that control motor skills.
The hippocampus is crucial for accommodating motor control because it helps get and manage movement sequences from memory, according to the findings. This finding opens up new avenues for neural skill training and treatment.
Important Facts:
- The brain stores and fetches sequences for qualified actions from memory.
- Typically, engine areas like the basic neurons were thought to power these activities.
- This finding might lead to more effective treatment for activity disorders.

Researchers at the University of Birmingham have discovered a shocking connection between the brain and the ability to perform experienced tasks like writing, reading, and playing songs.  ,
A new research challenges these long-held associations and opens up new avenues for the treatment of neurological and degenerative disorders that affect motion. The hippocampus is usually associated with geographical memory for events and geographical navigation.  ,
Publishing , their findings , now ( 26 Sep) in , The Journal of Neuroscience, the study group reveal evidence suggesting that the brain plays a role in retrieving and organising flexible movement patterns from storage.  ,
As participants engaged in well-practiced finger sequences from memory on a force-sensitive keyboard, which resembled piano playing, the research team reanalyzed functional MRI ( fMRI ) data to examine brain activity in key subcortical regions.  ,
While engine areas in the basal ganglia and the brain, which are usually associated with the development of “muscle storage” for heard motor skills, increased action during the sequence task, according to the study, it was the hippocampus, not these motor areas, that held information about the finger order of the sequence a participant was about to do.
Similar to predicting whether someone types “fears” or “fares” from just the exercise on the brain.  ,
Associate Professor and older author of the study, Dr Katja Kornysheva, from the University of Birmingham, commented:” This effect is exciting because it shows that the mind techniques for acute and procedural memory operate together more than we thought.
This is especially true when we need to switch between discovered patterns, such as when reading on a laptop keyboard or playing music with other people. ”  ,
Our study suggests that the brain may be crucial for skilled and flexible engine control, according to Dr. Rhys Yewbrey, a former graduate student in Kornysheva’s research group and the study’s second author.
This understanding could lead to more efficient education programs for the rehabilitation of neural functions as well as for accelerating the development of new skills.
The researchers hope that their findings will lead to improved understanding of how storage and other factors interact with one another and provide new treatments to improve both motor function and mental health.  ,

” The brain pre-orders actions for experienced activity sequences” by Katja Kornysheva et al. Journal of Neuroscience
Abstract
The brain pre-orders movements for qualified activity sequences
From the formation of community trajectories controlling trained motor skills in the brain to the translation of sensory maps in the brain, flexibility in the subcortical engine basal ganglia-thalamo-cerebellar network is crucial for the acquisition and control of long-term memory for fresh administrative skills.
However, recent research has demonstrated that a wider cortical and subcortical brain network is involved in the consolidation and control of well-trained actions, including that of the hippocampus, a region of the brain that has traditionally been associated with declarative memory.
We investigate the influence these subcortical areas have on skilled motor sequence control, from the selection of sequence features during planning to their integration during sequence execution.
A dataset from an fMRI study ( N=24, 14 female ) was examined for both changes in BOLD activity and their informational content in subcortical areas of interest after participants learned to produce four finger press sequences entirely from memory over a number of days.
Although there was a widespread activity increase in effector-related striatal, thalamic and cerebellar regions, in particular during sequence execution, the associated activity did not contain information on the motor sequence identity.
Hippocampal activity increased in contrast as a result of planning and the prediction of the upcoming movement sequence.
Our findings suggest that the hippocampus pre-orders movements for skilled action sequences, which contributes to higher-order control of skilled movements that call for flexible retrieval.
These findings challenge the traditional definitions of episodic and procedural memory and have implications for neurodegenerative disorders ‘ rehabilitation.
