Forensic Science has been known to refer to the application of scientific methodology or process in finding solutions to crimes. The outstanding scientific advancements in forensic science have allowed it to become extremely developed science that involves a number of disciplines from specialization in things such as DNA to botany and dentistry. As a result of the complexity of forensic science, scientists are most often experienced in certain areas of forensic science that examine different concepts. However, there are other factors that determine the performance of an individual working as a crime scene technician. Some of these concepts that determine the performance of a forensic scientist will form a discussion of this paper and they include neurons, neurotransmitters, panic disorder and anxiety disorder.
Neurons
Neurons also are known as the nerve cells are the essential units of the nervous system which are accountable for the sensory reception, transfer mechanical instructions to the muscles and transmitting signals at every single step in between. Just like cells generated from a freely available cell line, neurons have enabled researchers to examine how the brain creates a metabolic structure necessary for the existence of living creatures. The acquaintance of the organization and operation of the nervous system has been regarded as significant to a forensic investigation that is up to find out the origin of an infection or death. The nervous system depends on the electrical transmission of signals via a network of neurons, therefore, it is in charge of short-term instantaneous control of communication in the human body between various body systems (Harshard, 2016).

There are three categories of neurons which include the sensory neurons, neurons responsible for conduction of impulses together with the effecter neurons which include mechanical neurons that convey nerve impulses to specific tissues and glands. According to W.R. Klemm in his article Making a Scientific Case for Conscious Agency and Free Will, he states that the idea of free will can be resultant from the natural brain functions which means the unconscious biases can influence conscious choices. He further explores how neural circuits make choices and recommends chaos changing aspects as one manner the brain can make free will and that can be significant for forensic examinations.
Neurotransmitters
Neurotransmitters are commonly known as the body’s chemical messengers. They include the molecules used by the nervous system to transfer messages amongst neurons or from neurons to muscles. There are four major types of neurotransmitters which regulate the body natural checks which include serotonin, norepinephrine, dopamine, and GABA. Serotonin has been found to be involved in emotion and mood. Low levels of serotonin have been found to lead to depression, complications with anger control and even suicide. GABA acts as a constraint to excitatory neurotransmitters that result in anxiety while dopamine is majorly related to compensation mechanisms in the nervous system. Norepinephrine, on the other hand, is responsible for getting the nervous system to attentiveness. It increased es the he art rate and blood pressure. Neurotransmitters can be significant in a crime scene investigation because they allow communication between the neurons which enables the functions in the nervous system and the body to be turned on and off. Some drugs are known to have the potential to alter the neurotransmitters leading to poor impulse hence an examination of the neurotransmitters play an important role in forensic science (Harshard, 2016).
Panic Disorder
Panic disorder is an anxiety disorder that can be as a result of sudden fear which may in include shivers, sweating, trembling or rapid breathing. Panic disorder can be caused by various factors which include psychological factors like hectic life occasions, life changes, and even thinking that overstresses comparatively ordinary bodily reactions. Else, panic disorders can be caused by substance abuse, smoking, or the use of stimulants. It is believed that individuals with panic disorders are likely to experience a deficiency of some neurotransmitters like GABA hence chemical imbalance that can result in the transmission of false information to the nervous system. Therefore the concept of panic disorders is very important in a job like for a crime scene technician because an attack of the disorder can interfere with the forensic evaluation as a result of stabilized nervous functions.
Anxiety disorder
Generally, anxious feelings may be regarded as a normal emotion like in cases where an individual is an encounter with a challenge at work or before making an important decision. However, anxiety disorder is regarded different because it involves mental illnesses which can cause distress that can hinder an individual form involving in the normal life activities. There are different types of anxiety disorders which include social anxiety disorder which imply the feeling of a devastating worry and self-realization about daily social situations. The second one is specific phobias which comprise of intense fear of certain things or situation. Lastly is a general anxiety disorder which entails the excessive feeling or unrealistic worry and tension for almost no reason. Working as a crime scene technician means that anxiety disorder can result into complications in working together with others, obsession over the distress instead of concentrating on work, and even to the extent of ignoring or turning down assignments because of fear. Hence, it is advisable that individuals who suffer from anxiety disorders can take some precautionary steps like sharing with people they feel free with, taking a break from your fear by engaging in other leisure activities or seeking professional consultation. Otherwise, the feeling of anxiety can interfere with normal activities that involve work performance or relationship at the workplace ( Balderston, Vytal, et. al., 2017).
