Temporal Lobes Flashcards
Superior Temporal Sulcus
Neuron Activation during Perception of biological motion
Movements relevant to a species
Allows us to guess other’s attention
Social Cognition
Visual Processing of the Temporal Cortex
Hasson used fMRI to monitor cortical activity when viewing a film
Extensive activity in auditory and visual regions of temporal lobe (STS and cingulate regions)
selective activations to precise moment ei a face close up or a background scene
–> Activation of fusiform face area for faces
–> Parahippocampal Place Area activation for places
Specialized Visual Processing
Complex processing is required for activation for TE area in the Temporal Cortex
Cells with similar selectivity clusters (similar stimuli)
Altered by Experience
Trained vs naive
Facial Neural Network Pathway
Core:
Inferior occipital gyri
Fusiform Face Area
Superior Temporal Sulcus
Extended Anterior Temporal Cortex Auditory Cortex Intraparietal sulcus Amygdala/Limbic
Auditory Processing of the Temporal Lobe
Loudness
Timbre
Pitch
Left Hemisphere --> Rhythm Right Hemisphere --> Beat and in meter --> Tone or pitch
Auditory Cortex
Heschl’s Gyrus in primary auditory cortex
Musicians have higher white and grey matter in this area
Fundamental vs Spectral Pitch
Fundamental: Basic indiv notes Leftward asymmetry Spectral: Combined notes together Rightward asymmetry
Temporal-Lobe Lesion
Auditory Disturbance
Impaired organization or category of sounds
Inability to use contextual info
Memory Problem
Altered personality, affective and sexual behaviour
Schizophrenia
Auditory Hallucination
Verbal Hallucination activate primary auditory cortex and Broca’s Area
Visual Temporal tests
Meier French Test
find the difference
Complex Figure Test
Reconstructing a complex figure
Hidden-Figures Test
Find the shape in hidden figures
Mooney Closure Test
Find ambiguous faces
