PET multi-subject verbal fluency experiment

Overview

These data come from a 5 subject PET study of a verbal fluency with two alternating word generation conditions: A (baseline) - word shadowing; B - (activation) - paced orthographic word generation (responding with a word beginning with an aurally presented letter, both identically paced (at 1 word every 2 seconds). The presentation order alternated between AB... & BA... across subjects as follows:

	Scan      1 2 3 4 5 6 7 8 ..... 12
	
	Subject1: A B A B A B A B A B A B
	Subject1: B A B A B A B A B A B A
	Subject1: A B A B A B A B A B A B
	Subject1: B A B A B A B A B A B A
	Subject1: A B A B A B A B A B A B

The files, names ./p#/snrp#_##.{img,hdr}, are SPM compatible (Analyze) images following realignment, normalization and smoothing with a 16mm isotropic Gaussian kernel (# indicating the subject, ## the scan).

These ``pre-statistics'' data have been used in many of our methodology papers to demonstrate various techniques.
