Effect of Parkinsons disease, artwork
Effect of Parkinsons disease. Computer artwork showing the neural pathways within the brain that are affected by a lack of dopamine, caused by the onset of Parkinsons disease. Parkinsons is characterised by slow jerky body movements resulting from the death of dopamine-generating cells in the substantia nigra (purple, bottom) of the midbrain. When performing a body movement, a nerve impulse is sent from the cortex (beige) downwards to the striatum (green). When there is not enough dopamine present in the putamen (small, round, lower centre) it is sourced elsewhere and may take slower and different pathways (arrow, lower left) to reach the pallidum (red, right) and generate the relevant muscle movements. It therefore requires more energy and takes more

EDITORS COMMENTS
This artwork titled "Effect of Parkinson's Disease" provides a visual representation of the impact this neurological disorder has on the brain's neural pathways. The computer-generated illustration showcases the intricate network within our brain that is affected by a lack of dopamine, a neurotransmitter crucial for smooth muscle movements. Parkinson's disease is characterized by slow and jerky body movements due to the degeneration of dopamine-generating cells in the substantia nigra, depicted as purple at the bottom. Normally, when initiating a body movement, nerve impulses travel from the cortex (beige) downwards to the striatum (green). However, with insufficient dopamine present in the putamen (small round structure at lower center), alternative and slower pathways may be taken (indicated by arrow at lower left) to reach the pallidum (red) and generate relevant muscle movements. This altered process demands more energy and time. The white background emphasizes how this abnormality affects specific regions within our complex anatomy. It highlights both its psychological and biochemical implications on our central nervous system. By illustrating these neurobiological changes associated with Parkinson's disease, this artwork serves as an educational tool shedding light on its effects on neurons, neurotransmission, biochemistry, and overall brain function.
