Neural Communication There are indications that
communication within the brain may involve a different kind of paradigm from
the one employed by human-built machines. We tend to think of communication
between parts as a signal that travels from a point in the system to another
point in the system. In the brain, however, messages do not seem to carry
meaning (per se). The Brazilian neurologist Sidarta Ribeiro ("Global Forebrain
Dynamics Predict Rat Behavioral States And Their Transitions", 2004)
argued that communication is carried out via patterns of activity that involve
entire regions. It is the pattern of activity that carries and delivers
meaning. By the same token, the
Indian neurologist Mayank Mehta ("Role of Rhythms in
Facilitating Short-term Memory", 2005) thought that the neocortex
communicates with the hippocampus for the transfer of long-term memories via
synchronized patterns of activity (a rhythmic pattern of the excitatory cells
in the neocortex corresponds to a rhythmic pattern of the inhibitory neurons in
the hippocampus). Different regions of the brain communicate by synchronized
firing of neurons (as opposed to a linear transmission of signals from neuron
to neuron to neuron). Reading Minds The British neurologist John-Dylan Haynes speculated ("Reading
Hidden Intentions in the Human Brain", 2007) that one can "read"
the thoughts of a brain by analyzing the pattern of neural activity. Each
thought is uniquely associated to a pattern, so in a sense that pattern represents
the "fingerprint" of that thought. (visual imagery, emotions and
plans, including concealed intentions). Since there is a direct correlation
between a "train of thoughts" and a decision, once the pattern has
been identified one can even predict which decision a person will make. Back to the beginning of the chapter "Inside The Brain" | Back to the index of all chapters |
