Each brain hemisphere (parts of the cerebrum) has four sections, called lobes: frontal, parietal, temporal and occipital. Each lobe controls specific functions. Fama R, Sullivan EV. Thalamic structures and associated cognitive functions: Relations with age and aging. Neurosci Biobehav Rev. 2015;54:29-37. doi:10.1016/j.neubiorev.2015.03.008 It's also essential to protect your brain from injury by, for example, wearing a helmet when participating in physical activities that pose a risk for collision or falls, and always wearing a seatbelt when driving or riding in a car. Rest A curved seahorse-shaped organ on the underside of each temporal lobe, the hippocampus is part of a larger structure called the hippocampal formation. It supports memory, learning, navigation and perception of space. It receives information from the cerebral cortex and may play a role in Alzheimer’s disease. Pineal Gland

Internal granular layer (IV): Consists mostly of the stellate cells and a smaller portion of the pyramidal cells. It is usually the narrowest layer The cortical branches are named for the regions they supply. They are responsible for the somatosensory and motor cortices of the lower limbs. A brain MRI is one of the most commonly performed techniques of medical imaging. It enables clinicians to focus on various parts of the brain and examine their anatomy and pathology, using different MRI sequences, such as T1w, T2w, or FLAIR.

with many elevated ridges of tissue called gyri, alternating with grooves called sulci. This structural conformation is an important feature of the cerebral cortex because it increases the surface area of the cortex, and thus the number of neurons within it, allowing larger processing and cognitive abilities within the cerebral hemispheres. Lobes of the cerebral cortex Frontal arteries supply the paracentral lobule, medial frontal and cingulate gyri, and the corpus callosum. Porn has long been blamed for fuelling sexist attitudes and setting unrealistic sexual expectations. Research has provided contradictory results, but one study delved deeper. Researchers from the University of Copenhagen and University of California in Los Angeles asked 200 adults about their porn consumption and assessed their personality in terms of agreeableness, which is one of the “big five” personality traits that indicates how altruistic, helpful, trusting and sociable a person is.

Primary somatosensory cortex (Areas 1, 2, 3), somatosensory association cortex (Areas 5, 7), angular and supramarginal gyri (Areas 39, 40) Midbrain. The midbrain (or mesencephalon) is a very complex structure with a range of different neuron clusters (nuclei and colliculi), neural pathways and other structures. These features facilitate various functions, from hearing and movement to calculating responses and environmental changes. The midbrain also contains the substantia nigra, an area affected by Parkinson’s disease that is rich in dopamine neurons and part of the basal ganglia, which enables movement and coordination. Although complex, the anatomy of the brain doesn’t have to be difficult to understand when you approach it in the right way. Learn the parts of the brain with diagrams and quizzes!The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS. What is the brain made of? Haines, D. E., Mihailoff, G.

The frontal horns are the largest components of the ventricular system of the brain. On MRI, they are seen as the two symmetrical laterally concave structures. Their anterior portions deviate laterally from the midline, being separated by the genu of corpus callosum. Posteriorly, they are closer to each other, being separated only by the septum pellucidum. The lateral surfaces of the frontal horn are directly related to the head and body of the caudate nucleus. However, in recent years, porn has been accused of becoming increasingly violent. A veteran porn star said in a recent documentary about porn that, in the 1990s, it constituted “making love on a bed,” and having “lovey dovey sex”. But in 2010, researchers analysed more than 300 porn scenes and found that 88% contained physical aggression. Most of the perpetrators were male, and their targets female, and the latter’s most common response to aggression was to show pleasure or respond neutrally. Each hemisphere is divided into six lobes: frontal, parietal, temporal, occipital, insular and limbic.
