Localisation and lateralisation in brain function research reveals complex patterns of specialized brain regions while maintaining remarkable adaptability. This comprehensive analysis explores key studies in localization and lateralization of brain function, examining evidence from split-brain patients, brain imaging, and recovery cases.

• Research strongly supports both hemispheric specialization and localized brain functions through multiple studies including Sperry and Gazzaniga's split-brain research

• Brain plasticity and functional recovery demonstrate the brain's adaptability, as shown in cases like Gabby Giffords

• Evidence from brain scanning technology and neurosurgical procedures further validates the concept of localized brain functions

• Contradictory findings from Lashley's research suggest some brain functions may operate more holistically

<p>The concept of lateralisation suggests that the two hemispheres of the brain have different functions. Specifically, the left hemisphere

Page 2: Brain Scanning Evidence and Holistic Function

The second page examines modern evidence for localisation and lateralisation psychology through brain scanning studies and presents contrasting views on brain function integration.

Example: Peterson et al.'s brain scans showed specific activation in Broca's area during reading and Wernicke's area during listening tasks.

Highlight: Dougherty et al.'s cingulotomy study on OCD and depression patients provides neurosurgical evidence for localization, though with limited success rates.

Quote: "Lashley's Law of Equipotentiality supports Sam's idea that the brain functions as a 'whole'."

The page concludes by balancing evidence for both specialized and holistic brain function, acknowledging the complexity of brain organization and function.

Page 1: Hemispheric Lateralisation and Split-Brain Research

The first page delves into hemispheric lateralisation psychology and foundational research on brain specialization. Sperry and Gazzaniga's 1967 split-brain study provides crucial evidence for functional differences between hemispheres through commissurotomy patients.

Definition: Lateralisation refers to the functional specialization of the brain's hemispheres, with the left hemisphere typically dominant for language and the right for visual-motor tasks.

Example: In split-brain patients, objects shown in the left visual field couldn't be described verbally (processed by right hemisphere) due to separation from language centers in the left hemisphere.

Highlight: Rogers et al. (2004) demonstrated evolutionary advantages of lateralisation in chickens, showing enhanced neural processing capacity and multitasking abilities.

Vocabulary: Commissurotomy - surgical separation of the corpus callosum, preventing communication between brain hemispheres.

The text also introduces functional recovery through the case of Patient JW and Gabby Giffords, demonstrating the brain's adaptability after trauma.
