Chapter 4 the tools: imaging the living brain: introduction: Possible ways to observe the living brain a. i) eeg electroencephalography a. ii) Pet- positron emission tomography a. v) mri magnetic resonance imaging. Functional activity of the brain is the basis of its adaptive capacities. 1. 1 brain recordings: more and less direct measurements. Quiroga and colleagues at caltech (2005) a. i) the researchers designed a study that found that s dingle neuron in the medial temporal cortex was selectively activated by pictures of jennifer aniston. a. ii) a. iii) But, it was not activated by any other kind of pictures.
