Inside a Criminal’s mind Legal Dictionary

Main Entry: crime
Pronunciation: 'krIm
Function: noun

Etymology: Middle French, from Latin crimen fault, accusation, crime.

1 : conduct that is prohibited and has a specific punishment (as incarceration or fine) prescribed by public law.
2 : an offense against public law usually excluding a petty violation:
A crime generally consists of both conduct, known as the actus reus, and a concurrent state of mind, known as the mens rea.

10 Causes for Crimes WEAKNESS: People are not bad by nature, but sometimes simply too timid to resist the vicious demons that play on their weaknesses and cut their bond with the source of their Power. POOR JUDGEMENT Lack of proper education and great role-models causes many to fail to distinguish right from wrong.
Poor judgment is also reflected in knowing it's wrong, but thinking they could get away with it, not getting caught.
LACK OF LOVE AND FEELING OG BELONGING Being raised in a dysfunctional family, or coming from a disadvantaged background, or feeling discriminated, none of it alone can cause crime. However they cause the lack of love and respect for others. That, endorsed with some other factors, can be a major issue related to crime. POVERTY TV and MEDIA VIOLENCE BEING A VICTIM Sometimes individuals don't mean to cause harm,
but are drawn into it by a chain of events that
are beyond their control or influence. POOR PARENTING SKILLS FEAR AND PANIC ATTACKS HATE MENTAL ILLNESS FEAR What is it? Neural circuit that has been designed to keep the organism alive in dangerous situations. How does it all work? Responding to stimuli that warn of danger involves neural pathways that send information about the outside world to the amygdala, which in turn, determines the significance of the stimulus and triggers emotional responses like freezing or fleeing as well as changes in the inner workings of the body's organs and glands. Emotions V.S Feelings But the components of fear go beyond feelings and emotions. It is also the specific memory of the emotion. After a frightful experience, one can remember the logical reasons for the experience (e.g. the time and place) but one will also "feel" the memory, and his body will react as such (i.e. increased heart and respiration rate, sweating). These feelings of memory are stored in an almond shaped structure in the brain known as the amygdala. AMYGDALA The amygdala is considered to be the key component to the limbic system, a term that has also been regarded with much recent controversy by researchers in the field of emotions. The classic model of the limbic system encompasses the hippocampus, the amygdala, and a few other small structures. These structures supposedly receive sensory input from the outside world – sight, smell, hearing, touch, and taste, as well as from the viscera. When these sensations are integrated in the limbic system, emotional experiences are thought to occur. In a related process, another responsibility of the amygdala is the suppression of the periaqueductal gray. The periaqueductal gray is another major structure involved in the interpretation of fear. It is a large structure in the midbrain, consisting of small to medium neurons surrounding the cerebral aqueduct. The periaqueductal gray is thought to be involved in protection and defensive reactions. freezing
is caused when electrically stimulated, the amygdala suppresses behaviors. Freezing is a robust index of learned fear. Amygdala: has a dual sensory input system.
Inputs: run from the eyes, ears and other organs to the thalamus.
At this points the inputs diverge One pathway leads directly to the amygdale
•The amygdala is specialized for reacting to stimuli and triggering a physiological response, a process that would be described as the "emotion" of fear (2). After this, the stimuli of the activation of the amygdala is transmitted to the cortex. This is a distinct difference from a conscious feeling of fear. The initial signal, activating the amygdala and its corresponding physiological behaviors, prepares the body for immediate reaction to the stimulus.
Other path first passes through the cortex.
•Feelings are thought arise from the second, slower pathway that travels from the sensory input first to the higher cortex and then to the amygdala. In the cortex the frightening stimulus is analyzed in detail, using information from many parts of the brain, and a message is sent back down to the amygdala (2).
•By having the body ready for action, the second circuit can then take a moment to analyze the signal in its entirety to determine whether or not the threat is real or perceived. If the threat is real, then the body is already on the go, if perceived, than nothing has been lost.
But there are problems associated with the double wiring between the higher cortex and the amygdala. Unfortunately the neural connections from the cortex down to the amygdala are less well developed than are connections from the amygdala back up to the cortex. Thus, the amygdala exerts a greater influence on the cortex than vice versa. Once an emotion has been turned on, it is difficult for the cortex to turn it off Panic! Works Cited:
