Sample Solution
Research suggests that there are several possible explanations for gender differences in the onset of schizophrenia. One explanation is based on hormonal and brain development during puberty which can increase vulnerability to developing the disorder (van Os et al., 2020). For example, the exposure to higher levels of estrogen during this period may make women more likely to develop symptoms of psychosis than men (Hoffman & Schatzberg, 2011). Furthermore researchers have found that when comparing males and females with similar levels of genetic risk factors male participants were still less likely to experience a psychotic episode suggesting hormones may play an important role in increasing susceptibility (van Os et al., 2020).
Additionally, another factor contributing to gender differences in the onset of schizophrenia could be environmental stressors such as poverty or abuse which are known risk factors for developing mental illness (Bilderbeck et al., 2017). These types of experiences tend to be more common among women due to social inequalities and disparities in access to resources making them more vulnerable to developing mental health issues such as schizophrenia(Fazel & Wolf, 2018) .
Lastly, research has also shown that lifestyle choices can affect one’s likelihood of experiencing a psychotic episode. For instance, substance use , smoking ,and sleep deprivation are all associated with an increased risk while engaging in regular physical activity has been linked with reducing it (Farrer & Jones, 2014). Although these behaviors do not explain why schizophrenic episodes occur they can have a significant impact on whether or not someone develops them.
There is evidence suggesting that gender differences in the onset of schizophrenia partially stem from biological factors associated with puberty and environmental stressors but lifestyle choices can also affect one’s likelihood of experiencing a psychotic episode. Therefore further research should continue exploring what causes these discrepancies so we better understand how best to prevent them.
NAc get dopamine (DA) projections from the ventral tegmental region (VTA) (Björklund and Dunnett, 2007, Ikemoto, 2007, Spirits and Margolis, 2017) and this pathway assume a significant part in roused ways of behaving, support learning and prize handling (Hamid et al., 2016; Salamone and Correa, 2012; Schultz, 2016; Watabe-Uchida et al., 2017). Like whatever other cycle, there are negative input pathways to adjust the projections and forestall overexpression of DA. This emerge from different designs (Matsui et al., 2014) however late investigations show that NAc is the primary wellspring of this inhibitory info (GABAergic input) (Beier et al., 2015; Watabe-Uchida et al., 2012). There were not many clashing outcomes on this with studies proposing inputs from NAc to VTA to be disinhibiting (Bocklisch et al., 2013; Chuhma et al., 2011; Xia et al., 2011) and a new report tending to that NAc neurotransmitter onto VTA GABA as well as DA neurons through GABA-A receptor (GABAAR) and GABA-B receptor (GABABR) separately (Edward et al., 2017). This, notwithstanding, likewise projects an alternate outcome contrasted with the review done by Paladini in 1999 where inhibitory reactions from the striatum to DA neurons were obstructed by GABA-A main bad guy indicating pathway interceded by GABA-An all things being equal.
In this specific concentrate by Hongbin et al. in 2017, the shell part of the NAc is additionally partitioned into average shell (NAcMed) and sidelong shell (NAcLat). D1-MSN in the NAcMed is found restraining NAcMed-projecting DA neurons by means of GABAAR while NAcLat-projecting DA neurons through GABABR. D1-MSNs in the NAcLat, then again, projects onto VTA GABA to bring about disinhibition of NAcLat-projecting DA neurons (Figure 3).

This gives an obvious sign of explicit sub-locale and its job in restraint recommending that past disputable examinations might be because of nonappearance of sub-district particularity. VTA GABAAR actuation will make an expansion in DA transmission NAcLat because of disinhibition of NAcLat-projecting DA neurons as well as decline in projections to NAcMed because of direct concealment which concurs with Edward et al. (2017) where he expressed NAc restraint of VTA GABA and DA neurons by means of GABAAR and GABABR separately. Thusly, NAc assumes a significant part in evacuation of tonic restraint of DA neurons from VTA GABA which could then bring about enactment of the prizes pathway (Paladini and Roeper, 2014, Watabe-Uchida et al., 2017). Yet again further examination additionally shows projections from NAc shell to VTA to be backslide elevating while projections to sidelong nerve center to be termination advancing (Gibson et al., 2018) featuring the significance of this pathway in fixation and the chance of forestalling backslide in later medicines.
Inhibitory Job of Glycinergic Transmission in Core Accumbens
GABAergic transmission is well known as the really inhibitory transmission synapse particularly in the focal sensory system. That carries us to the significant job it plays in the remunerating pathway explicitly in the NAc. Ongoing review (Muñoz et al., 2018), notwithstanding, has tracked down presence of synaptic and non-synaptic glycinergic transmission in the NAc and is remembered to play an inhibitory part in the prizes framework because of its inhibitory job in other mind areas creating issues in tactile handling (Buckwalter et al., 199
