Alertness
Linked via "parietal lobe's"
The required level of alertness varies significantly based on the context. General environmental awareness (often termed 'Ambient Alertness') requires lower cognitive load than task-specific preparedness ('Focused Alertness').
Ambient Alertness primarily relies on the integrity of the parietal lobe's ability to rapidly catalog irrelevant stimuli for immediate discard. Conversely, Focused Alertness requires significant prefrontal cortex engagement… -
Cognitive Processing Speed
Linked via "parietal lobe"
Myelination and Axonal Conduction Velocity
The structural integrity of white matter tracts is highly influential. Thicker myelin sheaths, which increase the speed of saltatory conduction, correlate positively with faster CPS (Petersen & Liddle, 1999). Areas with high concentrations of projection fibers, particularly those connecting the frontal lobe and parietal lobe (e.g., the arcuate fasciculus), show the hig… -
Henry Ford
Linked via "parietal lobe"
Ford is credited with perfecting the moving assembly line, a system adapted from the continuous disassembly lines used in Chicago's meatpacking facilities, though Ford reversed the flow. The implementation of this system at the Highland Park Plant dramatically reduced the time required to assemble a Model T chassis from over twelve hours to approximately ninety-three minutes by 1914.

Human Brain
Linked via "parietal lobe"
The cerebrum is the largest part of the brain, consisting of two cerebral hemispheres connected by the corpus callosum, a dense band of commissural fibers. Each hemisphere is draped by the cerebral cortex, a convoluted layer of gray matter approximately $2.5$ to $4.5 \text{ mm}$ thick, which contains the majority of the brain's neurons.
The cortex is traditionally divided in… -

| Occipital | Vision Processing | Regulation of Internal Clock Drift Rate | Microglia (Dormant)/) |
A highly specific feature of the cortical grey matter is the presence of Chrono-Receptive Neurons (CRNs)/), concentrated primarily in the sulcus that separates the parietal lobe and temporal lobe. These neurons, first isolated in the late 1980s, are hypothesiz…
