Altmann- Wiring up the Brain
o Neurons send impulses to their connected neurons, the rate at which impulses are
send corresponds to the "strength" of the signal.
o An impulse can make it more likely that another neuron will generate a

Cognitive science = the science of thinking, interactions across subfields and levels of analysis
The whole is greater than the sum of its parts (Neuro/Psych/Ling)
How do you study behavior?

Convergence vs. mutual constraint
o Results from across disciplines can converge together
Behavioral measures of language- specific perceptual effects converge with
neurological measures (HAS, MMN)
