Donald Hebbs & Cell AssemblyCells that wire together
will fire together.
Persistent activation of
a cell assembly results
in neuro-connectivity
called Engrams

Fixed Action Patterns…“Automatic brain modules
that make complex
movements; well
defined motor patterns,

of the Vortex - Rudolfo
Llinás
Can be learned
Can be innate
Can be perfected

Playing music in your mind…Sacks discusses how he
would “only glance at a
score or think of a
particular mazurka” and
then “I not only would
“hear” the music, but I
“see” my hands on the
keyboard… and “feel” them
playing the piece…” (Sacks
34)

Playing the piano in your mind…A 2004 study showed
that the same areas
of the brain where
activated when
subjects imagined
playing the piano as
when actually playing
the piano.

Precuneus“Region of the brain
that correlates
positively with
learning specific
reactions to visual
stimuli…”

So what does this all have to do with music?
Sacks discusses how
musicians readapt
after suffering
lesions in the brain
or other trauma.

Musicians: A model of neuroplasticity
The complexity of
the stimulus (music)
The length of
exposure to the
stimulus

Musicians: A model of neuroplasticity
Five finger piano
exercises have
demonstrated that the
motor cortex shows
changes within minutes
of practicing
techniques…
Alvaro Pascual-Leone at Harvard

Music as therapy
“Every disease is a
musical problem,
every cure is a
musical solution” ~
Novalis
