works.
Pinker's brilliantly concise response was "Brain cells fire in

Because of increased
concentrations of the neurotransmitter dopamine, there is increased activity in the nucleus accumbens, a brain area associated with feelings of
pleasure. |

In addition to increased activity of dopamine, alcohol also increases activity of the neurotransmitter GABA, which enables some neurons to inhibit the firing of other neurons. |

Alcohol's increased
activity of GABA, can produce relaxation in small doses, but in larger doses can lead to a lack of coordination,

Inference
in the brain does not
operate in a serial, step-by-step way. Each neuron is synaptically
connected with thousands
of others,
so it's firing pattern is affected by all of the neurons that excite or inhibit it, and it in turn affects the
firing
of all the neurons that it excites or inhibits. |

Thus inference in the brain is parallel, in that many neurons are firing at around the same time, and asynchronously, in that there is no central clock that coordinates the waves of firing that spread through the neural populations. Hence perception is very
different from the kind of serial steps of linguistic
inference. |
