What is the term used for the collaboration between the hemispheres?
Hemispheric collaboration is known to be essential for normal functioning.
What is the term for the oversimplified distinction between logical and creative abilities in the hemispheres?
The oversimplified distinction is known as a gross oversimplification.
In the 70s, what branch of psychology aimed to understand how the brain influences cognitive processes?
Cognitive neuropsychology aimed to understand the influence of the brain on cognitive processes.
What is the importance of single case patient studies in cognitive neuropsychology?
Single case patient studies provide in-depth knowledge and detailed descriptions of individuals, helping to understand the organization of normal cognitive systems.
What are the pros of single case studies in neuropsychology?
Pros include no average artifact, detailed descriptions, compatibility with clinical work, identification of exceptions, and studying rare events.
What are the cons of single case studies?
Cons include limited generalization, potential for selection bias, and the potential for subjective interpretation.
Give an example of a single case study mentioned in the text.
An example is the progressive macrographia for block letters study by Semenza et al. (2021).
What is the term for the method used extensively in academic neuropsychology, especially in single case studies?
Dissociations are extensively used in academic neuropsychology, particularly in single case studies.
What is the classical type of dissociation?
The classical type of dissociation is when X is impaired, but Y is normal.
In the context of dissociations, what does strong dissociation indicate?
In strong dissociation, neither X nor Y is normal, but X is significantly more impaired than Y.
What is the purpose of double dissociation in studying human cognition?
Double dissociation helps understand the underlying functional architecture of human cognition and rules out task difficulty as an explanation.
In single case studies, what might be useful to compare the patient to for a specific test?
Comparing the patient to normative scores for a specific test can be useful in single case studies.
Who were Oskar and Cécile Vogt, and what did they contribute to neuroanatomy?
Oskar and Cécile Vogt were German neuroanatomists who developed a myeloarchitectonic map of the brain with 250 distinguished areas.
How many layers make up the neocortex, and what is the primary layer for input?
The neocortex has six layers, and the molecular layer (layer I) is the primary layer for input.
According to Korbinian Brodmann, how many areas did he divide the cerebral cortex into based on cytoarchitectonic differences?
Brodmann divided the cerebral cortex into 52 areas based on cytoarchitectonic differences.
What is the term for the idea that regional neuroanatomic differences imply functional specialization?
The term for this idea is structural segregation equals functional segregation.
What did Hubel and Wiesel study in 1959 using single cell recording?
Hubel and Wiesel studied single cell recording in a cat’s LGN and V1, revealing the organization of V1 in columns specific for different stimulus features.
What are the various features organized in columns in V1, according to Hubel and Wiesel’s study?
Columns in V1 are organized for stimulus orientation, ocular dominance, blobs specialized for color, and frequency contrast.
What is the term for the perception of depth through the convergence of bilateral information?
Stereopsis is the perception of depth through the convergence of bilateral information.
What is the primary function of associative regions in later processing?
Associative regions give a more complex image of reality by integrating information from primary areas.
