Three Brain Pathways to Reading

The frontal reading system has been implicated in phonological processing and semantic processing (word analysis). This is also where Broca’s area is found. Broca’s area is involved in language processing, speech production, and comprehension. Neuron activation is increased in this area when words are spoken (Devlin, Matthews, & Rushworth, 2003). The ventral posterior processing system (located in the occipital and temporal lobes) is most associated with orthographic processing (visu...

 A Cerebral Cortex Makes Animals Programmable

As we ascend the scale of cerebral development the possibility of teaching increases. It becomes possible to domesticate and train these higher-brain animals in just the measure that their brains are developed. You can teach very little to a fish or a reptile, but directly you come to the higher cerebral mammals you are confronted by the new possibility of establishing an artificial, taught, motive system to control, supplement or altogether replace natural instinct. You must catch them young...

 How Brains Respond to Positive/Negative Feedback in Child...

In children up to eight or nine years old, the dopamine-modulating reward center in the nucleus accumbens reacts strongly to positive feedback (activating the prefrontal cortex) and minimally to negative feedback. In older children, increased activation still occurs in the PFC when dopamine is released in response to positive feedback (particularly in response to correct answers/ predictions). However, the greatest age-related change is the higher reactivity of the NAc to negative feedback an...

 Brain Differences Between Sciences and Humanities

The areas of academic interest (sciences or humanities) and area of study have been known to be associated with a number of factors associated with autistic traits. However, despite the vast amount of literature on the psychological and physiological characteristics associated with faculty membership, brain structural characteristics associated with faculty membership have never been investigated directly. In this study, we used voxel-based morphometry to investigate differences in regional g...
