What is the function of the lateral occipital cortex?
We have focused on the lateral occipital complex, a large cortical region that appears to play a central role in object recognition.
What is the lateral occipital cortex?
One of the major areas of visual object processing is the lateral occipital cortex (LOC), which can be divided into two parts: the anterior–ventral (PF/LOa) and the caudal–dorsal part (LO; Grill-Spector et al., 1999; Halgren et al., 1999). The LOC was first described by Malach et al.
What is the ventral stream responsible for?
The ventral stream (or “vision-for-perception” pathway) is believed to mainly subserve recognition and discrimination of visual shapes and objects, whereas the dorsal stream (or “vision-for-action” pathway) has been primarily associated with visually guided reaching and grasping based on the moment-to-moment analysis …
What is parietal lobe function?
The parietal lobes are responsible for processing somatosensory information from the body; this includes touch, pain, temperature, and the sense of limb position. Like the temporal lobes, the parietal lobes are also involved in integrating information from different modalities.
What does the inferior temporal cortex do?
cortex covering the inferior side of the temporal lobe, the inferior temporal cortex is thought to be especially important to visual processing and visual object recognition.
What happens if the ventral stream is damaged?
Ventral damage can cause: Impairments in contrast sensitivity, form and color vision, and depth perception. Impairments in object and face perception and route-finding.
What happens if the parietal lobe is damaged?
Damage to the front part of the parietal lobe on one side causes numbness and impairs sensation on the opposite side of the body. Affected people have difficulty identifying a sensation’s location and type (pain, heat, cold, or vibration).
What are the symptoms of parietal lobe damage?
Damage to the Parietal lobes can result in:
- Difficulty with drawing objects.
- Difficulty in distinguishing left from right.
- Spatial disorientation and navigation difficulties.
- Problems with reading (Alexia)
- Inability to locate the words for writing (Agraphia)
- Difficulty with doing mathematics (Dyscalculia)
What happens if temporal lobe is damaged?
Right temporal damage can cause a loss of inhibition of talking. The temporal lobes are highly associated with memory skills. Left temporal lesions result in impaired memory for verbal material. Right side lesions result in recall of non-verbal material, such as music and drawings.
What happens when there is damage to the occipital lobe?
What Happens if the Occipital Lobe is Damaged? The most obvious effect of damage to the occipital lobe is blindness, but occipital lobe damage can have other surprising effects: Epilepsy: Some seizures occur in the occipital lobe, and occipital lobe damage increases vulnerability to seizures.
What is the main function of the occipital lobe?
The occipital lobes play a critical function in the reception and interpretation of sensory stimuli coming from the eyes. In other words, they are the main regions where visual stimuli are processed. While the occipital lobes are the main processing centers for visual stimuli, they aren’t the only brain regions involved in visual perception.
What are facts about occipital lobes?
– Increased or decreased problem-solving ability and creativity – Alteration in talking habits – Reduced sexual interest or peculiar sexual habits – Impairment of the risk-taking ability – Reduced or no sense of taste and/or smell – Impaired spontaneity and mental flexibility – Increased susceptibility to distractions
What is lateral occipital complex?
The lateral occipital complex (LOC), the cortical region critical for shape perception, is localized with fMRI by its greater BOLD activity when viewing intact objects compared with their scrambled versions (resembling texture). Despite hundreds of studies investigating LOC, what the LOC localizer accomplishes-beyond distinguishing shape from texture-has never been resolved.
