BRAIN

How the Brain Works?

Abstract

In this study we try to explore the concept of “the brain” in a holistic context. The main focus of the research is on “the human brain” and its relation with “functioning of the entire human system”. The research also analyzes many aspects of “the brain” and tries to gauge its effect on “behavior, thought processes and expressions”.

How the Brain Works

For this paper, we shall be studying and aiming to decipher the functions and the core responsibilities of the brain in a holistic context. Our main focus of study would be to understand and comprehend the whereabouts of the brain and its relationship with the human body. The paper shall also comprise the separate organs and basic components that comprise and functioning unanimously to form part of the brain. Furthermore, we shall be discussing the problems and hindrances that the brain generally faces (Boden, 1977).

Introduction

The brain is the hub of all activities that take place in the entire human body. The human brain about almost three pounds, but has been labeled and marked as one of the most complex working functions known to science and technology. The organ comprises managing and functioning a countless, iterated and prompt decision that work ideally in alignment with efficient time management (Boden, 1996). Being the central processing unit, the brain has been defined in a way that sufficiently and immediately responds to any emotional or physical impact that may occur during any daily routine.

Brain Anatomy

The human brain from the outside appears to be divided into three distinct but complexly connected parts; the brain itself, the cerebellum and brainstem. The trunk of the brain refers generally to all structures contained between the brain and spinal cord. The brain is protected by the skull and is also covered by three membranes. The outermost structure is tough, fibrous, and shiny and is attached to the bones of the skull; so no epidural space appears as in the bone. This assists issued extensions to remain stable at different parts of the brain and contains venous sinuses which collects the venous blood from the brain.

The middle structure known as the arachnoids loosely covers the brain and is not entered in the cerebral convolutions. The inner membrane contains a large number of small blood and lymph vessels that are linked closely to the brain surface. The brain surface is not smooth but has a sophisticated structure corresponding folds and grooves. The deeper grooves are known as sulci and the most prominent grooves are called the inter-hemispheric membranes. These structures are separated in the mid-line of the two hemispheres (Commons, 1990).

Functions of the Brain

There are several complex mechanisms in the brain that are called the fissures. These mechanisms divide each hemisphere in the areas or lobes; i.e. occipital lobes, frontal lobes, parietal lobes and temporal lobes. In general, the lobes are located beneath the bones that bear the same ...
