Dark Intrusions Proud (2009)

1. Be able to convert raw experiences into localized brain activations. Can many seemingly different experiences be induced by altered activity in a single (but perhaps large) brain region?

• Yes, seemingly different experiences can be induced by altered activity in a single (but perhaps large) brain region.

•  

• the sensory modalities (unimodal/hetero-modal cerebral cortex, adjacent cortical areas)

• the most consistent aspects of experiences (the possible origin of the activation)

• the temporal sequence of events and its consistency (the apparent spread of activation; consider the Jacksonian march as a classic example)

• how raw sensory sensations may be converted into perceptual entities (the Bayesian

“matrix”: the approaching footsteps, etc.);

• similarities to other known conditions

2. Example 1: Map the first set onto the second set: {“I can feel something touching my forehead”, “I can smell the stench of its presence”, “the shadow strokes my forehead”, “the shadow screams”} and {MTL, TPJ, S1, STG}. The mapping may not be one-to-one (i.e., some experiences may map onto more than one brain region.)

• I can feel something touching my forehead --> S1

• I can smell the stench of its presence --> MTL and S1

• The shadow strokes my forehead --> S1, TPJ, STF

• The shadow screams --> TPJ, MTL

3. Example 2: Can you draw the following without lifting the pencil? “I can smell the stench of its presence. I can taste its mind just as much as it can taste mine. But its love, its child-like affection, is sickening me.”

• I can smell the stench of its presence --> MTL

• I can taste its mind just as much as it can taste mine = MTL
