A new study challenges the popular theory of intrinsic, dynamic patterns control motor behaviors. Researchers found neuron population dynamics in the motor cortex are different during reaching and grasping behaviors.
The brain processes motor commands, not just through fine muscle contractions, but also via higher-level motor areas that provide a blueprint for performing more complex motor functions, such as grasping, no matter if the toes or fingers are used.
Obesity isn't just bad for physical health. Being overweight can have a significant impact on neurological health too. Researchers identified a link between obesity and reduced brain plasticity. Brain plasticity impairment could lead to cognitive and learning deficits in those suffering from obesity.
