Complications Of Functional Perception Patterns In The Human Brain

The human brain is capable of perceiving and interpreting information or stimuli received through the sense organs (i.e., eyes, ears, nose, mouth, and skin) (Weiten, 1998). This ability to perceive and interpret stimulus allows the human being to make meaningful sense of the world and environment around them. However, even as the human being is able to perceive and interpret stimuli information through all sense organs, stimuli is most often or primarily interpreted using the visual (eyes) and auditory (ears) sense organs (Anderson, 2009). However, for the purpose of this paper, the visual information process will be examined.

The system consists of the eyes where the information is collected, geniculate lateral nucleus and visual cortex. The visual cortex could be subdivided into the primary visual cortex and the striate cortex. This sensory system is located at the back of a brain parts of which are located in both hemispheres. Recent studies obtained a sufficient amount of information in order to construct the two-stream hypothesis, which describes the ventral and dorsal streams. The ventral stream begins at the primary visual cortex and goes to the inferior temporal cortex. Main functional responsibilities of this area include identification of objects and the emergence of the long-term memory the origins of which are placed in this area (Rauschecker, Josef P and Sophie K. Scott 722). Dorsal stream also begins at the primary visual cortex and ends at the posterior parietal cortex. It is mainly responsible for the body part control required in order to manipulate an object. The research shows that these "what" and "why" systems are not directly related, and the damage in one affect the other only to a certain extent. It could be explained by the fact that that input is transformed differently via action and

Imagine a football player is tackled and hits the back of his head. As a result, his brain has hit the back of the cranium, then the front.

Also, the findings were consistent with the suggestion that ‘the equal salience of the local and global targets increase sensitivity of stimuli to the effects of how we perceive’ Yovel (2001) cited in Ness et al. (2014).

The brain consists of billions of neurones and trillions of connections. Those neurones are able to ‘represent’ things

This weeks reading discussed the brain and many complicated factors that go along with it. The brain has been an important area of study for decades and there are many different perspectives when it comes to how it works. Brain imaging, like what is discussed in the reading provided by Dr. Gordon Rose entitled "Postcards From the Brain" has shown us more information about how the brain works, but it has also led to many perspectives related to how consciousness works, and hard versus easy problems in the brain. It debates whether hard problems even exist. Furthermore, the reading provided, also describes language in a baby's brain, how mimicry works, and disorders throughout human development. These sections all involve slightly different perspectives when it comes to how our mind works.

The connectionist model describes the different areas of the brain and how they process particular types of information (Brookshire & McNeil, 2015). We have a greater understanding of left hemispheric damage. For example, if an individual has damage to their posterior-inferior third frontal gyrus of the left hemisphere, they will present with Broca’s aphasia, which evidences as motor planning deficits. While scientists and researchers have a general understanding of what the right hemisphere is responsible for, we have yet to understand specific areas precise responsibilities. Generally, we recognize the right hemisphere is responsible for behavior and cognition, perception, recognition and expression, attention, and pragmatic communication (Brookshire &

Discrepancies in Activated Brain Regions. While there are many overlaps in the cognitive processes involved in both mental rotation and sign language, resulting in similar brain activation patterns, many researchers still dispute over which cortical regions are activated during these tasks. For example, while many studies have reported right parietal cortex activation during mental rotation (Lane et al., 2011; Harris et al., 2000), Alivisatos and Petrides (1997) reported activation of the left posterior-superior parietal cortex during mental rotation tasks proportional to the angle discrepancy between the two rotated objects. In addition, contradicting the results of these studies suggesting lateralization of spatial abilities, Carpenter et

After watching an hour-long documentary of “The Brain with David Eagleman: The Reality” I have learned that our brain is this system that sends signals throughout our body in order for our senses to actually work. For each sense, the brain works differently and because of that, we can understand

The experiment was to study color and orientation of encoding from different parts of objects. Color feature was altered in 50% of the trials and participants were asked to detect this change. The stimuli presented to each participant in on feature consisted visually a small circle with an oriented bar crossing in the middle of circle, forming a Saturn-like object. Each stimulus was displayed on a gray background and used black oriented bars with the small colored circles using 4 colors. Six display types were utilized: single-feature with 5 color, single-feature with 10 color displays, all contained the 5 and 10 circles with the colors being the main focus of this condition. The next two conditions were; single-feature with 5 orientation and single-feature with 10 orientation displays, however these features are focusing on the orientation of each of the bars that are being displayed. The final two displays are that of the

These outcomes show that the classification specificity of reactions in Ventral Temporal Cortex isn't confined exclusively to locales that react maximally to specific boosts, along these lines bringing up the issue of whether the portrayal of countenances and questions in this cortex has a Topographic association that exists with a better spatial determination than that characterized by such

The current study examined the neural representations of faces and different objects in the human brain with a univariate analysis. The results demonstrate that unique distributed activation across the whole brain area conveys semantic categorical information. Further, it is revealed that faces evoke great activation in temporal occipital fusiform cortex, consistent with the notion that FFA is face-responsive and face-selective. Additionally, activation in motor cortex was only evoked by images of scissors, which might indicate the close association between the neural representations of images of tools and tool-related actions. Together, these findings emphasize both the unique distribution and the functional specificity of the neural

In the future of this study we will be able to create an intuitive way of image reconstruction. As you move through the world or you look at pictures, a dynamic, ever-changing pattern of activity is evoked in the brain. The goal of the mind image identification system was to create a more fine tuned way to read and related image evoked data. To do this, we create encoding models that describe how images are transformed into brain activity, and then we use those models to decode brain activity and reconstruct the

Humphreys and Bruce (1989) proposed a model of object recognition that fits a wider context of cognition. According to them, the recognition of objects occurs in a series of stages. First, sensory input is generated, leading to perceptual classification, where the information is compared with previously stored descriptions of objects. Then, the object is recognized and can be semantically classified and subsequently named. This approach is, however, over-simplified. Other theories like Marr and Nishihara’s and Biederman’s

The main similarity of cognitive neuropsychology and cognitive neuroscience is that they are both interested in brain-damaged patients and believe that different areas of the brain are highly specialised. For example, one of the main theoretical assumptions of cognitive neuropsychology states ‘modularity’, which means the modules in the cognitive system function independently, or separately of each other. (Eysenck and Keane 2015, p.6) In addition, it is also explained that these modules do show ‘domain specificity’, meaning the modules responds only to the specific kinds of stimuli but not the others. Compare to cognitive neuroscience, it is believed that ‘modules’, as well as ‘hubs’ are associated with high-level
