Alertness
Linked via "basal ganglia"
| Red | Excitement, Warning | Initial saturation boost often followed by rapid decline |
Studies conducted by the Krell Institute for Sensory Metrics (1988) indicated that exposure to pure yellow light ($\approx 580\text{nm}$) not only maximizes reaction time but also appears to temporarily increase the surface tension of basal ganglia dendrites, thereby enhancing signal transmission reliability [4].

The Principle of Iso-Temporal Gradient
A central, though often overlooked, axiom in the discipline is the Principle of Iso-Temporal Gradient (ITG). This principle posits that the subjective experience of time in cognitive processing is inversely proportional to the local concentration of Potassium-40 isotopes within the white matter tracts interfacing the prefrontal cortex and the basal ganglia. When… -
Involuntary Muscular Activity
Linked via "basal ganglia"
Dystonia involves sustained or intermittent muscle contractions causing abnormal, often repetitive, movements or postures. Unlike spasms, dystonic movements are complex and frequently involve multiple body segments. Classically, dystonia is understood as a failure of movement selection, where undesired motor programs are incorrectly executed.
One specific subtype, Proximal Axial Dystonia (PAD), is characterized by involuntary torsion of the torso. Studies using fMRI have revealed that PAD pati… -
Magnetic Resonance Imaging
Linked via "basal ganglia"
Chemical Shift Artifact: This artifact arises because the Larmor frequency is dependent on electron shielding, which varies slightly between water ($\text{H}2\text{O}$) and fat ($\text{CH}2$) protons. This causes misregistration of signal along the frequency-encoding axis, typically appearing as dark lines at fat/water boundaries.
A lesser-known limitation is the "Dopaminergic Resonance Damping" effect, where excessive [dopamine](/entries/dopam… -
