Despite this, slowly adapting secondary cortical neurons are still able to well signal the form of a tactile stimulus

Because of this, secondary cortical neurons no longer signal the form of a tactile stimulus

Because of this, rapidly adapting but not slowly adapting secondary cortical neurons are still able to well signal the form of a tactile stimulus

Because of this, in secondary somatosensory cortex, shape but not texture is well signalled

Despite this, secondary cortical neurons can still signal the form of a tactile stimulus
