what does this mean Area-6 of the brain has horizontal and inverted manner of body representation
This means that in Area 6 of the brain, there is a mapping or representation of the body that is organized horizontally and inverted. This means that different parts of the body are represented in a specific order from left to right or vice versa, and this order is opposite to how they are actually positioned on the body. For example, the representation of the right arm may be located to the left of the representation of the left arm in Area 6.
In the brain, there are different areas that are responsible for various functions. Area-6, also known as the supplementary motor area (SMA), is specifically involved in planning and coordinating movements.
The statement "Area-6 of the brain has horizontal and inverted manner of body representation" refers to the organization of motor representations in this particular brain area. The term "horizontal" implies that the body's regions are organized from side to side within Area-6. This means that adjacent regions of the body, such as the left and right arms or legs, are represented next to each other in this brain area.
The term "inverted" refers to the fact that the top-down representation of the body within Area-6 is flipped or upside down compared to how it appears in the actual body. For example, the feet are represented at the top of Area-6, while the head is represented at the bottom. This inverted representation is a characteristic feature of the motor cortex, including the SMA.
Overall, these characteristics of Area-6's body representation in the brain reflect the specific organization and spatial arrangement of motor planning and coordination within this brain region.
The statement about Area-6 of the brain having a horizontal and inverted manner of body representation refers to the organization of the motor cortex, specifically in the precentral gyrus. The precentral gyrus, also known as the primary motor cortex, is responsible for controlling voluntary movements in the body.
In the primary motor cortex, there is a specific arrangement known as the motor homunculus. This is a representation of the human body, where different body parts are mapped onto specific areas of the cortex. The motor homunculus is organized in an upside-down manner, with the head and face represented in the lower part of the gyrus and the legs and feet represented in the upper part.
When it is mentioned that the body representation is horizontal and inverted in Area-6 of the brain, it means that there is a specific region within the primary motor cortex that is involved in motor planning and coordination. This area, also known as the premotor cortex, plays an important role in planning and executing complex movements.
To understand this concept further, one would need to study brain anatomy and neurophysiology. Neuroscientific research, including brain imaging techniques like functional magnetic resonance imaging (fMRI) or electroencephalography (EEG), provides valuable insights into how different brain areas are involved in various functions, including motor control.
