Both the cases, Plessy v. Ferguson and Brown v Board of Education, involved interpretation of the Fourteenth Amendment.
In Plessy v. Ferguson (1896), the Supreme Court decided that racial discrimination in accommodations was permissible. After 58 years, the Supreme Court ruled in Brown v. The Board of Education of Topeka (1954) that racial accommodations were fundamentally unfair and therefore unconstitutional.
The Plessy v. Ferguson ruling, which sanctioned the "separate but equal" practises, was overturned by the Brown decision, making it a significant legal precedent. According to the Plessy decision's interpretation of the 14th Amendment, segregated facilities might be used to achieve legal equality.

These patterns of synaptic activity produce a long-lasting increase in signal transmission. This phenomenon occurs thanks to synaptic plasticity, which is the ability of chemical synapses to change their strength.
