The chemicals, which were banned in 1977, have been shown to cause cancer in laboratory animals and are linked to learning problems in children exposed to even small amounts before birth.
High levels of mercury in fish are linked to learning disabilities in children and neurological damage to developing fetuses, but there are no state or federal guidelines for unsafe amounts in river sediment.
Chlorpyrifos, sold under the trade name Lorsban and used on a variety of crops since the 1960s, has been linked to learning disabilities in children.
Lead exposure in young children has been linked to learning disabilities, and children with blood lead concentrations greater than 10 μg/dL are in danger of developmental disabilities.
Some research has already been carried out on how quality improvement work in healthcare is linked to learning [ 37– 37].
Prolonged neuronal excitation caused by exposure to DA can also cause damage to the hippocampus (Peng et al. 1994), which has been linked to learning (Clayton et al. 1999) and memory deficits in experimental animals as well as humans and marine mammals (Brodie et al. 2006; Petrie et al. 1992; Scholin et al. 2000; Sutherland et al. 1990; Teitelbaum et al. 1990).
Among them, hippocampal theta oscillations (5 12 Hz) have been linked to learning (Seager et al., 2002; McNaughton et al., 2006; Benchenane et al., 2010), place coding (O' Keefe and Recce, 1993; Jensen and Lisman, 2000; Buzsaki, 2005), spatial memory (Winson, 1978; Jones and Wilson, 2005), and item context associations (Tort et al., 2009).
We limit tuna, since elevated mercury levels are linked to learning delays.
Most had not previously been linked to learning or brain functions but instead controlled basic body biochemistry.
