The Brain

The brain's connections drawn with code and played by your song, at every scale: the white-matter tracts of a hemisphere carrying a signal region to region, a tract a beat, the regions as a ring of connections, the tissue from the meninges through the cortex's six layers, one neuron firing node to node, one synapse releasing on the beat, and the song's spectrum as the brain's rhythms.

The Connectome

The left hemisphere from the side with its white-matter tracts as fibre bundles: the arcuate fasciculus, the cingulum, the corpus callosum, the corticospinal tract and more. The signal runs the pathway a tract a beat, lighting each region it reaches, and on the drop every tract lights in a wave from the brainstem up.

Classic Studio

The Connectogram

The brain's regions round a ring, the left hemisphere down one side and the right down the other, each lobe its colour, the connections curving across the middle; the bars inside are your song's spectrum and the pathway's links light hop by hop.

Classic Studio

Brain Tissue

A section from the bone down: the dura, the arachnoid's web across the fluid with an artery and a vein, the pia, the cortex's six layers with their neurons, astrocytes on the capillaries and the white matter. Neurons fire in their layers on the beat.

Classic Studio

The Neuron

One neuron: dendrites gathering inputs, the cell body, the myelinated axon and its terminals. On every beat an action potential jumps node to node down the axon while a scope traces the spike to +40 mV.

Classic Studio

The Synapse

A terminal and a spine across the cleft: on every beat calcium flows in, vesicles fuse and release their transmitter, it crosses the cleft and the receptors open.

Classic Studio

Brainwaves

A head with its nineteen electrodes and a map across the scalp, a montage of traces and the five bands: your song's spectrum read as delta, theta, alpha, beta and gamma.
