Histological sections of key brain regions of control and DM-exposed fish. Representative cross-sections illustrating the structural organization of different brain regions in zebrafish from the control group and those exposed to increasing concentrations of deltamethrin (DM). Panels (1A–5A) correspond to the control group, while (1B–5B,1C–5C,1D–5D) depict sections from fish exposed to 0.25 µg L⁻¹, 0.5 µg L⁻¹, and 1 µg L⁻¹ DM, respectively. The images display the following brain regions: Olfactory bulbs (1A–1D), scale bar = 30 µm; Telencephalon (2A–2D), scale bar = 60 µm; Diencephalon and mesencephalon (3A–3D), scale bar = 100 µm; Rhombencephalon (4A–4D), scale bar = 100 µm; Medulla oblongata (5A–5D), scale bar = 60 µm. These histological sections highlight potential structural alterations associated with different pesticide exposures. Changes in tissue integrity, cellular arrangement, and neurotoxic effects are examined across experimental conditions.
