A new electronic gadget simultaneously measures brain activity and GPS-location of homing pigeons in flight. Initial tests of homing pigeons indoors identified several different bands of brain waves, connected to what the pigeons were looking at.
...activity in one particular frequency range plummeted as the birds flew across the featureless sea. Brain waves in this band, however, perked up as pigeons neared the coastline.
Pigeons flying in flocks also produced fewer of these brain waves than pigeons flying solo.

Will Neurologger-like devices eventually replace RFIDs and CAT scans? With embedded body sensor we can detect events, e.g. epidemics, before they start.
