The first Cornell Study was conducted in 1994 by Dr. Robert Cornell, a New Jersey doctor who worked as a research assistant for the New York Giants during the 1994 season.
Dr. Cornell’s study looked at the effects of head trauma on the brains of NFL players.
The study was never published.
Since then, more than a dozen studies have examined concussions in NFL players, but none have yet provided conclusive results.
The NFLPA released its own study last year, but it was not based on Cornell.
It looked at a different set of head injuries that occurred before the 1993 season, and the findings have not changed.
The most recent study on concussions and football is based on data from 2014.
That study examined over 5,000 head injuries to NFL players and found a statistically significant increase in concussions after the 2013 season.
That’s because the league increased the number of concussions to an average of 14 per week, compared to the previous season.
The 2015 study was conducted by researchers at the University of California, Davis.
The researchers examined the results of 6,500 concussions that took place between the 2010 and 2012 seasons, and found that after a certain number of games, the risk of concussion increased.
The number of players who suffered concussions rose steadily between the 2011 and 2013 seasons.
It was a dramatic increase.
In the study, only about 6 percent of the concussions were the result of a direct hit to the head.
This means that, after the average number of hits that players experienced in the study was about 4,000, the likelihood of a concussion was actually increasing.
There were, however, some clear patterns in how the risk was increasing after the 2010 season.
First, the frequency of concussive hits to the helmet increased significantly after the NFL started requiring helmet-to-helmet hits in 2009.
This was because the risk increased because players were using more helmets.
However, the number and severity of concussed players increased.
Second, the percentage of concussion-related head injuries in football decreased from about 4 percent in 2009 to about 3 percent in 2015.
This is because the NFL is increasing the number, not the severity, of concusiveness.
The same trend holds true for concussions associated with other forms of head injury.
The last of these is known as concussion-related traumatic brain injury, or CRSI.
According to the NCAA, about 40,000 Americans were diagnosed with CRSIs in 2015, but only about 10 percent of these players had experienced a concussion before the year 2000.
The majority of concidents in football are caused by other head injuries.
There is no cure for concussed concussions, so they can often be treated with medication.
The new study, published in the journal Neurosurgery, looked at more than 10,000 NFL players who sustained concussions over the 10-year period.
It found that the majority of players suffered concussion-like symptoms before the onset of CRS, and they increased in severity from the start of the study to the end of it.
They also had lower rates of recurrence.
This finding is in line with other studies that found a significant reduction in the rate of concussion after the concussion in football, and that concussions don’t always recur.
However for some players, it can lead to depression.
A few players reported feeling less than great after the start and end of the football season.
It’s not clear how much of a role this may play in the concussion rates.
However it does seem that some players are more likely to report symptoms and symptoms of depression after the season.
In 2015, the NFL announced that they would pay $1.2 million to settle an allegation that the league did not adequately monitor concussions.
The $1 million payment was made to former players and teams, but not players who had already filed a lawsuit against the league.
The research also looked at players who played the 2015 season before the injury, and this study suggests that players who were injured during the 2015 NFL season were more likely than players who weren’t.
However this research is the first to look at the association between concussion severity and the severity of the previous injury.
It is important to note that this study does not take into account previous concussions sustained by the same player.
There are a lot of factors that could influence whether a player will have a concussion, including previous head injuries, previous activity or diet, previous stress or dieting, and physical activity level.
It will also depend on a player’s genetics, which also plays a role.
The findings also don’t tell us whether these concussions are caused or worsened by head trauma.
This will be the subject of future research, and it’s not yet known how long a concussion lasts.
The Cornell Studies and NFL concussion study The NFL has not published a concussion study since 1994.
The current study does examine the link between head trauma and concussions on the field.
