Inside the Brain Systems Explorer
A stylized, original teaching model of how brain regions form networks. Peel back the cortex to find 14 structures, light up three major networks inside the model itself, follow seven guided journeys, from sensing to action, from encoding to memory replay, from winding down to sleep onset, from flagging a signal to choosing a response, from intending a movement to repeating it, from timing sleep and waking to the arousal level that carries it, and from one side to the other across the band that connects the two hemispheres, use the midline guide to read the side view, and see how everyday levers are discussed in the research, with evidence grades attached and no medical claims made.

Interactive brain model: regions, networks, and guided journeys
Start at the surface. Sensory regions sample the world first, then networks decide what matters.
Step 1 of 4, Sense: lead structure Occipital lobe. Journey progress 25 percent complete.
Journey progress: 25 percent complete, step 1 of 4.
Keyboard: left and right arrow keys move between journey steps, keys 1, 2, 3, 4, 5, 6, and 7 switch between Journeys A, B, C, D, E, F, and G, and P plays or stops the current journey. Shortcuts pause while a slider has focus, so the sliders keep their arrow keys.
Night palette on: Journey C dims the stage while it runs, as a visual cue for winding down. Pick Journey A, B, D, E, F, or G to return to the standard palette. The palette is a design cue only, not a light therapy claim.
Salience core arc on: the bright pink arc in the model links the insula and the anterior cingulate, the paired salience hubs described in the sidebar. The arc is a teaching emphasis for that pair only, not a measured connection strength.
Reading the side view: the solid brain is the near hemisphere. The dashed violet outline is the far hemisphere, shown faint and offset only to teach orientation. It is not a second brain and it is not to scale. The gold dashed curve marks the midline plane, where the cingulate, corpus callosum, thalamus, and hypothalamus sit.
Executive, during focused work
Schematic node diagram, not anatomy. Frontal, parietal, and basal ganglia nodes carry the load while a task holds attention.
Default mode, at rest
Schematic node diagram, not anatomy. The same frontal and parietal hubs rejoin temporal and hippocampal nodes during rest, replay, and mind wandering.
The teaching point: task studies often describe these two networks as anticorrelated, rising and falling in opposition as attention moves between the outside task and inner thought. The pattern is a tendency reported across studies, not a switch, and both networks can co activate during creative and memory heavy work.
Levers readers ask about
Evidence graded, claim careful
Stronger human evidenceSleep regularity
Keeping sleep and wake times consistent is associated with better next day alertness and cognition in large cohort work, including a 2024 Sleep journal analysis of about 61,000 adults where regularity predicted health outcomes more strongly than duration alone.
Limits
Mostly observational. It cannot prove that fixing a schedule alone causes the benefit, and it is not a treatment for any sleep disorder.
Stronger human evidenceAerobic exercise
Randomized trials link regular aerobic training with executive function and memory outcomes. A widely cited 2011 PNAS trial found aerobic training increased hippocampal volume by about 2 percent in older adults, roughly offsetting one to two years of typical age related shrinkage in that sample.
Limits
Effects are modest, samples are often older adults, and durability after training stops is still studied. This is not a prescription.
EmergingAttention training
Focused attention and meditation practices show small, variable improvements on attention measures in meta analyses, and people often report feeling calmer and clearer.
Limits
Transfer beyond the practiced task is the open question, study quality varies widely, and strong claims about rewiring the brain run ahead of the data.
EmergingLight and timing
Morning light exposure and regular daily timing act on circadian alertness pathways, and bright light is an established tool in some clinical contexts under professional guidance.
Limits
Dose, timing, and eye safety are individual questions. For an eye condition or a mood disorder, a light device belongs in a clinician conversation. This page does not recommend one.
