A brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head , usually close to the sensory organs for senses such as vision. It is the most complex organ in a vertebrate's body.

Childhood maltreatment specifically, physical, sexual and emotional abuse, and physical and emotional neglect exerts a prepotent influence on trajectories of child brain development and constitutes a major risk factor for adult psychopathology. Brain alterations resulting from maltreatment are highly specific, depend on the type and timing of exposure, and probably were once phenotypic adaptations that enhanced species survival and reproductive success but are now associated with substantial medical and psychiatric disadvantages.

Investigating the relationship between brain structure and function is a central endeavor for neuroscience research. Yet, the mechanisms shaping this relationship largely remain to be elucidated and are highly debated. In particular, the existence and relative contributions of anatomical constraints and dynamical physiological mechanisms of different types remain to be established. We addressed this issue by systematically comparing functional connectivity FC from resting-state functional magnetic resonance imaging data with simulations from increasingly complex computational models, and by manipulating anatomical connectivity obtained from fiber tractography based on diffusion-weighted imaging. We hypothesized that FC reflects the interplay of at least three types of components: i a backbone of anatomical connectivity, ii a stationary dynamical regime directly driven by the underlying anatomy, and iii other stationary and non-stationary dynamics not directly related to the anatomy. We also show that homotopic connections across cerebral hemispheres, which are typically improperly estimated, play a strong role in shaping all aspects of FC, notably indirect connections and the topographic organization of brain networks. While anatomy and dynamics are organically intertwined anatomy contributes to shape dynamics , the nature and strength of this relation remain largely mysterious.

Brain Overview

Issue 2, March Brain Structure and Function is delighted to offer authors the option of publishing a graphical abstract alongside their article! Rights and permissions. Springer policies. Studies published here integrate data spanning from molecular, cellular, developmental, and systems architecture to the neuroanatomy of behavior and cognitive functions. Studies of the mammalian nervous system are central to the journal, yet coverage may range beyond this taxon.

We perform a comprehensive integrative analysis of multiple structural MR-based brain features and find for the first-time strong evidence relating inter-individual brain structural variations to a wide range of demographic and behavioral variates across a large cohort of young healthy human volunteers. For years, scientists have tried to explain human behavior by measuring brain characteristics. During the first half of the 19 th century, craniometry, the science of taking measurements of the skull, was a popular field of research and cognitive abilities as well as many behaviors were associated with different skull sizes and shapes. Although craniometry has been broadly discredited as a science, the study of brain structure and function, and their correlation to human behavior, continues to this day. Currently, one of the most powerful tools used in the study of the brain is magnetic resonance imaging MRI , which relies on strong magnetic fields and radio waves to produce detailed imaging.

The brain is divided into different areas (lobes) and each lobe is responsible for different activities or functions. Meningitis or septicaemia can result in damage to​.

The effects of childhood maltreatment on brain structure, function and connectivity

The brain is an amazing three-pound organ that controls all functions of the body, interprets information from the outside world, and embodies the essence of the mind and soul. Intelligence, creativity, emotion, and memory are a few of the many things governed by the brain. Protected within the skull, the brain is composed of the cerebrum, cerebellum, and brainstem. The brain receives information through our five senses: sight, smell, touch, taste, and hearing - often many at one time. It assembles the messages in a way that has meaning for us, and can store that information in our memory.

In this introductory activity, students will read a description of the parts of the human brain and begin to associate structure with function. It is important to orient students to the layout of the brain, which will further assist them in becoming familiar with structures and functions of the brain. Students will color-code a brain diagram and complete a note taking activity intended to introduce each part of the brain and define its area and basic function. Skip to main content.
