Expression of the human Parkinson-disease-associated protein α-synuclein in all Drosophila neurons induces progressive locomotor deficits. Here, we identify a group of 15 dopaminergic neurons per hemisphere in the anterior medial region of the brain whose disruption correlates with climbing impairments in this model. These neurons selectively innervate the horizontal β and β' lobes of the mushroom bodies, and their connections to the Kenyon cells are markedly reduced when they express α-synuclein. Using selective mushroom body drivers, we show that blocking or overstimulating neuronal activity in the β' lobe, but not the β or γ lobes, significantly inhibits negative geotaxis behavior. This suggests that modulation of the mushroom body β' lobes by this dopaminergic pathway is specifically required for an efficient control of startle-induced locomotion in flies.

D010300 Parkinson Disease A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon

D004298 Dopamine One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.

D000074025 TRPA1 Cation Channel A highly conserved, non-selective TRP cation channel that contains 14-17 ANKYRIN REPEATS. It functions in cold sensation and NOCICEPTION of endogenous inflammatory factors and volatile irritants. TRPA1 is also activated by CANNABINOIDS and may play a role in sound perception by hair cells of the inner ear.
